Name: , DL Section: Last First Office Use Quiz 2 Physics 7B Winter 2010 Jan. 20, 2010 1. Consider a simple vascular system, such as the circulatory system of an earth worm shown in schematic form in the diagram below. Assume that the cross sectional area of the artery ( A A )is equal to that of the vein( A V ) ; assume that the heart (pump) has a larger cross sectional area ( A H ) and that the sum of the cross sectional area of all of the capillaries ( A C ) is less than that of the artery. a) What are the relative volumetric flow rates of the artery, capillaries, vein, and heart. State all values in terms of I V , and indicate which are

State all values in terms of v V , and indicate which are larger, smaller, or the same. c) Assume that the artery and vein each have very little resistance, but that the capillary net has resistance R . Assume that the heart has strength P H = E pump /V. What is the pressure at the middle of the capillary network (State in terms of P V )? 2 2 1 1 2 A IR-) ( 2 1 IR-v A v V E v y g P V E V E Pump Pump External...
