Team meetings were professional and efficient Meeting Log January 17, 2005 - We met as a group to work on the Scientific Method report, Library report, and the quiz. January 18, 2005 - Nate and Rahul met to finish up the Scientific Method report. January 27, 2005 - We met as a group to discuss how we would set up our snapshot and to take our group picture. Fibruary 5, 2005 - We met at Star Bucks today!!! We just had a run through of the lab write up that is due this wednesday. We need to also not forget about the questions that are due this friday (Feb. 11) that the lab questions are due. February 6, 2005 - Some of us met Adam in Jordan Hall 004 for questions we had on the case study and hints/tips on how to prepare for the exam. He was really helpful and cleared up a few cloudy things for us all. If things go well we all (007) should get A's..maybe a B or two or us "not so perfect ones" like myself. February 9, 2005 - We met as a group at the library to work on the discussion questions and prepare for the exam. Productivity was low. Meeting was adjourned early due to conflicting schedules. February 10, 2005 - We all attended the review session which proved very helpful. Wishing it had been earlier in the week. February 16, 2005 - Met at library to update group snaps shot. February 20, 2005 - Group met at the main library to work on the upcoming pre-lab as well as set up a time and place for a meeting the following day. February 21, 2005 - Met at Nate's apartment to review the case studies and what had been discussed in class. February 28, 2005 - Met at the main library to work on the lab report. March 3, 2005 - We all attended the review session. March 9th, 2005-We meet at the library and discussed our concerns about the course and also completed the team snapshot. March 29, 2005 - Some of us attended the review session. March 31, 2005 - We all attended the review session. April 7, 2005 - We met at the library to update our team snapshot. April 20, 2005 - We attended the review session for Exam 4 April 21, 2005 - The group attended Nilay's review and then met afterwards to discuss plans for the final presentation and snapshot. April 25, 2005 - We met to work on our snapshot. April 26, 2005 - We met to work on our presentation and do a run through of it.

Team Meetings When the team met it seemed like the meetings usually took longer than planned because we usually talked for a while before we started on what we needed to work on. It was not unusual for some team members to be missing from the meetings but we usually got done what we had intended to do. At one point we attempted to have more team meetings to go over material but that did not last long. We had less meetings as the semester progressed.

Team Interaction Update 1/27/2005 So far Team 007 has shown excellent communication among members via email and by phone. Meetings in the Main Library have been productive and efficient. The team dynamic is operating such that ideas are well shared and decision making is a group process. To this point there have been no conflicts of character, work-ethic or goals. Everyone is cooperative and morale is high. Good expectations for Team 007. 2/16/2005 Due to inadequate performance on exam 1, Team 007's morale is low. This should have been expected in lieu of poor preparation in the weeks prior to the exam. Our group plan of action is currently being restructured. It will include regularly scheduled group meetings to both review material and complete assignments. We plan to do better individually to stay on top of the readings and also to make more visits to office hours. Despite the poor performance seen thus far, Team 007 believes that with these changes and a more team oriented mentality, success is still attainable.

We watched a lot of ER Class Time Class time was not utilized effectively by our team. Some team members did not find class helpful and so they did not attend class regularly as other team members did. This often affected group discussion in class. When we were all there to have group discussions in class they were not usually focused on the topic and did not seem to benefit the team learning. As a result, coming to class was not an effective tool for our group.

Office Hours Some of our group members regularly attended office hours and it seemed to benefit them quite a bit. Not all of our group took advantage of office hours but the ones that did found it beneficial.

Homework Some group members felt that the class assignments were not well geared towards the goal of the class. The labs and prelabs did not particulalrly help towards understanding material on an exam, except for the respiration lab, which was rather beneficial. The one assignment that did help and especially becuase Nilay went over the answers the day before this assignment was due was the discussion excericises.

Review Sessions As the semester progressed the review sessions given earlier in the week seemed to be more helpful. They were very helpful for our group to pull together some of the information discussed in class and solidify key topics. Individuals often had many trouble areas cleared up at these review sessions.

Maybe a little physiology? What have we been learning? Body Fluid Compartments Extra cellular fluid is compased of the fluid present in the blood and in the psaces surrounding cells. Only 20is blood, or the plasma while the rest is between the cells and called interstitial fluid. The intracellular fluid is the fluid inside the cells and cells regulate their activity by maintaining differences in fluid composition across the cell membrane. Water accounts for 60of normal body weight and 2/3 of it is in intracellular fluid about 28L in a 70kg person. Only about 3L of the body's water is in the blood plasma Baroreceptors The carotid sinuses in the neck serve as pressure recepotors called baroreceptors. There is also one in the arch of the aorta called the aortic arch baroreceptor. The two corotid sinuses and the aortic arch make up the arterial barorecpeotrs. Afferent neurons travel from baroreceptors to the cardiovascular control centers. The rate of discharge at the receptors is directly proportional to MAP. The more the baroreceptors fire due to high MAP, they cause the parasympathetic nervous system to decrease the heart rate and the overall contractility of the heart muscle. The integrating center is the medullary cardiovascular center which determines the action potential frequency to the vagus nerve. The baroreceptor reflex also effects angiotensi II generation and vasopressin secretion. If the MAP is too little, you have an increase in plasma concentration of both the hormones which raise the MAP by constricting arterioles. The baroreceptors respond to prolonged changes in pressure and so cannot set long term arterial pressure. The major factor for long term regulation is the blood volume, which influences venous pressure, venous retgurn, EDV, and so on. An increase in blood volume increases arterial blood pressure and an increase in blodo pressure causes the secretion of salt and water by the kidneys. This is an example of negative feedback and is a long term determinant of blood pressure which can only set at a value at which the blood volume is stable. Heart Chordae tendinae bind the papillary muscles to the tricuspid, the right AV valve, and the bicuspid, the left AV valve to the ventricles. Semilunar valves are pulmonary and aortic valves. Only 1% of cardiac cells do not function in contration. The parasympathetic nervous system releases acetylcholine. Acetylcholine binds to muscarinic receptors, while norepinephrine binds to mainly beta andrenergic. Action potential SA node causes depolarization of atria at about the same time. Propagation of action potential through AV node is slow and requires about 0.1s so that atrial contraction can be completed before ventricular excitation. AV node and the bundle of his are th eonly electrical link between atria and ventricles. The resting membrane is more permeable to potassium than sodium. So the resting membrane potential is closer to the potassium membrane potential (-90mV). Depolarization is due mainly to opening of voltage-gated sodium channels in positive feedback mechanism and K permeability decrease. After Na channels close, there is a plataue of depolarization because K permeability is below resting value and calcium membrane permeability increases. This was an example of ventricular contractile cells. .a

LEARNING GOALS Develop a Functional Knowledge of Human Physiology Operate Efficiently as a Team Improve Group Problem-Solving Skills

It all starts with physiology EXAM ONE COVERAGE Exam one's primary focus was on homeostasis and compartmentalization of the cardiovascular system. We were asked to look at blood composition, hemodynamics, electrical activity, and the autonomic system. We also learned form lab how to read and give an EKG as well as interpret the results. These skills will be utilized on the test in forms of case studies. EXAM ONE RESULTS Exam one proved to be challenging to the group members. Our main problem was lack of preparation. Most members of our group were inexperienced in group work, so we did not mesh together right away. We also had a problem with the format of some of the test questions. We felt a few of the questions were ambigous and we had a hard time answering them. With time we believe we will be able to work harder and earn a higher ranking in the class. RESULTS FROM EXAM II Exam scores were much improved from Exam I. The highest level of improvment was seen as the team's ranking went from 12th to 1st in the class. This can be directly attributed to the extra time spent outside of class studying and attending office hours. Regular attendance in class also proved to be an asset, however most benefit came from office hours and independent studying. Three people scored above average with 84's on the exam resulting in the high class ranking. COMMENTS ON EXAM II The collective feeling was that some of the points stressed in class were not on the exam. For example, the excitation-coupling mechanism that was repeatedly pointed out was not a major factor on the exam. Furthermore, many questions on the exam focused on capillary filtration and colloidal pressure; however, the cases presented in class and discussed in office hours did not deal with those issues. The numerous cases-which, to our understanding, are a reflection of the material covered for the exam-seemed to involve calcium-channel inhibition/excitation and other mechanical heart functions. Class time and office hours stressed homoestatic functions and reactive processes in the heart. For example, what happens during a hemmorage? How is the heart rate effected? What happens to the stroke volume? We understood all of these ideas and consequently answered these questions fairly well on th exam. Furthermore, all questions regarding mean arterial pressure were answered comfortably. EXAM THREE COVERAGE Exam three shifted the focus away from cardiovascular physiology and concentrated on the renal system and renal functions. For this portion of the course, we focused on the renin-angiotension-aldosterone system, congestive heart failure, renal failure, acid-base balance, secretion and reabsorbtion, and lastly glomerular filtration. COMMENTS ON EXAM THREE We wish we had more case studies to prepare for the exam. We should also emphasize more time on learning the details and less on other activities. COVERAGE ON EXAM FOUR Exam four turned out rather well for our team. One of our group members got above a hundred percent, while the majority of the others were in the 90's. The topics on this exam were mostly respiratory. The exam focused on altitude cases, obesity, sleep apnea, obstructive respiratory disorder, and restricitive respiratory disorder. COMMENTS ON EXAM FOUR We all felt that this exam was fair. It was what we expected going into the exam and studying for it, although we wished that Dr. Schlegel had been there during this exam because we were having some conflicts between the AI's on some questions. Now its time to get ready for our final project. Should be fun.

Things to Improve on for Exam 2 Individual Study Utilization of Office Hours In-Class Participation on Case Studies Group Meeting Productivity & Attendance Things to Improve on for Exam 3 Come more prepared to office hours. Read material BEFORE class. Move up further in classroom...fight for your right to learn. Things to Improve on for Exam 4 Continue to improve upon previous goals. One method some group memebers chose to do differently for exam 3 this was started studying a few days earlier than the previous exam. Several other group members attended office hours more regular basis.

The body is a beautifully complicated thing SNAPSHOT PRESENTATION The challenge in these snapshot presentations is the same for every team. How can they best illustrate their semester-long progress to their peers in simply 5 minutes? The five people that make up team 7 decided to tackle this challenge via a 2-pronged approach. Both areas of our presentation covered the questions that most people would ask about a team experience where grades were still given as individuals. 1st. In what ways have the individual's cognitive processes evolved in relation to physiological input? 2nd. In what ways did the team-based learning approach aid in the individual's progress? Powerpoint presentation This is the power point presentation that team 7 performed for the class. It covers the points mentioned above and really stresses some of the most important physiological concepts we all learned. *Some sound files may not work due to PC updating.

REFLECTION Rahul: I was studying for the MCAT during this class and my biochemistry classes really kept me busy. However, after speaking with Dr. Schlegel following the first exam, she convinced me to stay in this class and try to integrate physiology in with biochemistry and especially studying for the MCAT. My grades on the exams instantly went up and never went as low as the first exam. I really wish that we could drop the lowest exam grade because then I think that my grade in the class would be higher than it is. I was really hoping for between an A- and A in this class, and I still have hope because there are still around 400 points to come from the final presentation, the final exam, and this snapshot. Our team has put in a lot of effort in the final presentation and the look of this team history. We did not want our final presentation to be the the cliche presentation, that is standing up there and introducing yourself and what you did. Rather, it was important for us to take a more direct approach and explain what we learned and how that process has made our larger thinking change. We even laid out preliminary plans for a video, but we realized that the video would be unable to address clearly our motives and reasons for creating a final presentation. A power-point presentation on the other hand was concise and to the point. The final exam is the next thing I have to study for, and I am going to study hard, I just wish I knew a little bit of what it was going to be like. All of the other four exams have been a certain way and I am used to that way now, but for this final, things have been revamped and no one really knows what to expect. I expect it to be a little bit easier because I am better with knowing facts rather than applying them, but I enjoyed that experience also. My favorite thing about the class was the opportunity it gave me to get to know new people and really connect with them. I really am happy with the group I was given: we all work hard, everyone is really polite and respectful, and when needed everyone comes through. My greatest memory of this class will be the second exam when we were sitting in class and saw our team average was the highest in the class. This was probably because after the first exam team morale was just so low and we even had low self-esteem. I hope I see everyone soon...clearly, I'll see everyone on Monday. :) Megan:I honestly don't remember studying as hard for a class as I did this one. I spent a good portion of my semester stressed out about this class and what was going on in it. The beginning of the semester was a little rough for me due to some personal problems and I think this is part of the reason I did poorly on the first exam. That and I did not know how to prepare for the test. After knowing what to expect for the first exam and making some changes to how I studied the rest of my exams were a lot better. Overall I am happy with the group that I was given and the opportunity to get to know them better. I'm not a big fan of doing everything in a group but I did enjoy getting to know everyone and I think it actually helped me on studying. In not wanting to let my team down I studied much harder for the exams than I probably would have on my own. I have begun to prepare for the final but since it is set up a little different than the previous exams I'm not sure how this is going to go. I think it might be better because I struggled with the case studies a little bit. Maybe we can have a group reunion sometime next semester!!!! Lauren: My reflections regarding physiology... I remember walking into the classroom on the first day of the semester, and thinking, oh no, what have I got myself into? I have always been the type of person to concentrate on my studies individually rather than work with others. This class has taught me, that it is okay to rely on others, and my team has taught me plenty. My only regret about this class was that I feel like my grade does not completely reflect my academic abilities. I never fully grasped the concepts that case study type of tests convey. I found it hard to connect my knowledge about physiology and apply that towards case studies. The main thing I remember from the class was the helpless feeling I had after exam one. The team's morale was pretty bad. We ranked last in the class, and everybody was pretty down about it. My first instinct was to drop the class, and I think if this class was individual I would have. Rahul was also thinking about dropping the class. At that point, I felt like I had a duty to remain in the class, and in the end, Team 007 stuck it out, and I came out with good friends as well as a strong background in physiology. Final wishes to group 007.. Megan- Good Luck working at the zoo this summer. Thank you for always being in class to find out whats going on, sometimes my alarm clock just doesn't go off! Nate- I think whatever profession you decide to persue, you will do awesome in it! I think you held the team together with your knowledge about physiology, and it was comforting to have you in the group. Rahul- Good luck in a couple years going to med school. The way you study, and the way you make time to study (eg. no sleep for days on end) is impressive. It was nice to count on you to pull through in the end. Karl- I enjoyed listening to your re-caps of what people said two seconds earlier. "Hey maybe you should write an outline on notecards or something" Dr. Schlegel, Nilay, and Adam.. Group 007 would like to thank you for all your dedication to your students! Karl: Reflecting back on P431...... My first impression on the first day of this class was not a good one. I was not sure how I would fit in as a grad student working with undergrad's. Rumors were spread that everyone in this class were pre-med majors and that they all had a snobish attitude and anybody who was not a pre-med major could not tell them anything. Well, needless to say this was not the case at all. We all had different majors and intrest and I think only one of us was determined to go to medical school. We all were pretty much excited with working with each other once we found out who was who. The first exam was tough for us all. It set the learning curve right and we saw where we stood....last. We knew we had to make fast improvments for us to be successful in this class. We made a turn around and did better on the rest of the exams and rest is history. Overall, I loved working with my group members. As I said before I was not sure how I would fit in being a grad student, but I found my place as being the "resource manager". We all played a vital part and contributed to our overall success. Thanks guys for your hard work and good luck to all... Hey Rahul....wake up!! Nate: What can I say, this was probably the best class I have ever taken (except for "Downhill Alpine Skiing in Aspen" of course) and since I am graduating next weekend, that says a lot. And no, this is not me trying to "suck up." In no other class have I felt so motivated to read the material simply because I wanted to know more. There is something about physiology, how it directly relates to my life and the lives of those I know, that creates a personal interest in it. And despite the initial adjustment period to the case study approach, particularly on the exams, I feel like that really facilitated an actual understanding of the material - that is, understanding beyond learning a bunch of facts. A secondary result was that everything we learned is tied together by logic, and so will not be easily forgotten. I expect this to prove immeasurably useful in preparing for the final exam. Learning with the case studies and working through the diagnoses has also prompted in me (for the first time) an interest in medical school. While I had been planning on becoming an Optometrist, it just doesn't seem that would offer the same broad scope (both in study and in practice) that would present itself pursuing an MD (not to mention the variety of opportunities that would follow). So while I am still by no means decided on any specific career path, I have definitely expanded the possibilties as a result of this class. Finally, the group structure of this course has been a new and useful experience for me. While at times it seemed more a hassle than anything, trying to accomadate schedules and arrange meetings, looking back I definitely would prefer such inconveniences rather than "going it alone" as it would be. It has been great getting to know the members of Team 007, and learning how to function as part of a group will surely prove useful in the near future. Also the team approach made the entire course seem more personal, particularly in a class of nearly 60 people, and I feel like I have come out not only with a better understanding of physiology but with several good friends who I am looking forward to celebrating with in the near future. Good luck to everyone on the final exam Monday; I'll see you there.

Roles as Individuals Nate - Team Captain Rahul - Go-To Guy Lauren - Communicator and Coordinator Megan - Class Connection Karl - Resource Manager

Group Work Turns to Delegation: We began the semester by meeting and working as a team, but by the end of the semester we began to work individually and delegate tasks, particularly regarding the lab reports. The tasks were usually delegated as: Nate - Introduction Rahul - Conclusion and "Putting it all together" Lauren - Methods and Materials Megan - Results Karl - Provided Resources This method proved sufficiently effective at completing the lab reports, however any collaborative learning that may have been gained via group work was lost.

Bart uses google Useful Resources We have found many resources to be helpful in our studies this semester. One particularly important resource was the online journal database www.pubmed.com. This website was particularly helpful in our lab on exploration of Resources and References in the Sciences. We also found the Academic Search Premier and Harrison's Online helpful when researching topics covered in the prelabs.

Examples of some of our work: Below please look at some of the items team 7 has been working on this year. The two main assignments in class were labs and discussion excercies. Respiratory Discussion Discussion excercises were due before each exam and really helped in creating a sort of check point to make sure your knowledge was complete. Heart Rate Lab The heart rate labs was one of the experiments performed on the Friday laboratory lessons. Labs stressed the importance of the scientific method.
