Mode of propulsion?
Veins areCapacitance vessels(high compliance)with valves for unidirectional flow
Arteries are low compliance, so any increase in volume increases pressure.
MAP = CO x TPR
Negative feedback control:stimulus, receptors, afferent pathway(s), integrator, efferent pathway(s), effector(s)response(s)
What happens to the set point for MAP during exercise?
A Neuroscientist in New Orleans
MAP = (HR x SV) x TPR
Mean Arterial Pressure = Cardiac Output x Total Peripheral Resistance
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.
