Document Summary

Review last 3 lectures of cardiovascular physiology (vascular function) Question 1: increases in which of the following parameters will increase blood flow: difference in pressure between two point of a vessel, resistance of a blood vessel, radius of a blood vessel, viscosity of blood. Blood flow = pressure gradient/ resistance through blood vessel. Resistance = ln/r^4 **n = viscosity** ** r = radius to power of 4 ** Pg 188 graph: arterioles, aorta, capillaries, venules, none of the above. Question 3: while working in the lab, you discover a new type of blood vessel that has a high smooth muscle content and think walls compared to their diameter. Pg 190-193: capillaries, venules, arterioles - have lots of smooth muscle, small diameter and thick, large artery, large vein walls. Question 4: calculate the net fluid movement across the capillary with the following values for starting forces (kf = 1) pg 197***
