Compare blood pressure and velocity in arteries vs. veins vs. capillaries. a. Why is it beneficial to have low blood velocity in the capillaries? b. There is blood pressure within capillaries, resulting in fluid loss. Is any of the lost fluid returned directly to the capillaries? What happens to the rest?
