  2. 1QQ # 26 for 8:30 • Suppose an arteriole was clamped shut? How would this alter the Starling forces in the capillaries downstream from this arteriole? How would this affect bulk flow in the capillaries? • Based on your knowledge of Starling forces, describe 3 changes that would increase capillary filtration.

  3. 1QQ # 26 for 8:30 • Suppose an arteriole dilates. How would this alter the Starling forces in the capillaries downstream from this arteriole? How would bulk flow be affected? • Based on your knowledge of Starling forces, describe 3 changes that would decrease capillary filtration.

  5. S 2 Figure 12.44 Veins areCapacitance vessels(high compliance)with valves for unidirectional flow Arteries are low compliance, so any increase in volume increases pressure.

  6. S 3 Fig. 12.53 MAP = CO x TPR Negative feedback control:stimulus, receptors, afferent pathway(s), integrator, efferent pathway(s), effector(s)response(s)

  7. S 4 Fig. 12.54 What happens to the set point for MAP during exercise?

  8. Story Time S 5 A Neuroscientist in New Orleans

  9. S 2 MAP = CO x TPR MAP = (HR x SV) x TPR Mean Arterial Pressure = Cardiac Output x Total Peripheral Resistance

  10. S 6 Test 3 Hemorrhage Diagram One the back side of this page, create a diagram for the following. Your response must be confined to the reverse side of this page and you must write legibly. Your response will count 15-20% of the grade on Test 3 and should require no more than ten minutes to complete at the beginning of the test. Beginning with a loss of about 1 liter of blood from a vein, diagram the early events associated with hemorrhage and the negative feedback responses to hemorrhage in a well-organized diagram. Write legibly! Completeness, accuracy, and detail, together with the proper sequence earn maximal points. The following abbreviations can be used: AI, AII, JGA, mAChR, Hct, Q, SV, EF, RBC, HR, EDV, ACh, ANH, ADH, CO, TPR, EPO, VR, MAP, EPI, NE, SAN, aAdR , bAdR, Symp (sympathetic), Parasymp (parasympathetic), PV, r (radius), Pc, fAP (frequency of action potentials.) Any other abbreviations must be defined. "If in doubt, write it out!" Use single headed arrows (→) to indicate sequential relationships and doubled-stemmed arrows to indicate increases or decreases.
