Document Summary
Blood vessel notes: the tunic inima of blood vessels, like the endocardium of the heart, is made of simple squamous epithelium, the tunica media consists of smooth muscle that is regulated by the sympatheic nervous system. It is used to regulate the diameter of the lumen: elasic arteries absorb most of the shock when the heart ejects blood. These pressures strongly afect the exchange of luids across the capillary wall. Low capillary pressures are desirable because capillaries are fragile and high pressures would rupture them. Calculate net iltraion pressure (nfp) at the arteriole end of the capillary. The net iltraion pressure would now be negaive as a result of the blood pressure drop, which would result in litle or no luid moving across capillary walls into the intersiial luid at the arteriole end. Net iltraion pressure (nfp) for the arteriole end of the capillary = (hp c +
