BIOC33H3 Lecture Notes - Superior Vena Cava, Pulmonary Circulation, Heart Valve
Document Summary
Labs: practice labs, will have to submit lab reports. Simulated labs: software available at bookstore, older editions are fine, only difference, prior to edition 9, it was on cd, only need to submit 5 assignments - simulated labs, data analysis, questions, etc. Labs 6, 5, 7, 9, 10: due fridays before 4 pm. Human physiology ii: 4 main topics, cardiovascular physiology: Start by looking at basic electrical activity in area called sinoatrial (sa) node heart"s pacemaker. In heart, have cells that function as nerves, modified to conduct electrical activity. Pacemaker potential, pacemaker ap and cardiac ap have some similarities as neuronal ap. Electrocardiogram (ecg) - shows how heart is working. Allows us to interpret abnormalities in the heart: electrical axis of the heart - overall direction by which electrical activity flows in the heart over the course of an entire cycle of contracting and relaxation. Function of heart rate (beats/min) and stroke volume (amount of blood pumped per beat)
