Which of the following about bulk flow is TRUE? a) Net filtration occurs near the venous end of the capillary while net absorption occurs near the arterial end. b) Hydrostatic pressure pulls fluid into the capillary while osmatic pressure forces fluid out of the capillary. Oc) When moving from the bloodstream into the interstitial fluid, bulk flow is termed absorption. d) When moving from the interstitial fluid into the bloodstream, the process is termed filtration. e) Net filtration occurs when hydrostatic pressure is greater than colloidal osmotic pressure.
Which of the following about microcirculation is TRUE? a) The wall of a metarteriole is partially surrounded by pericytes. Ob) Precapillary sphincters contribute to the tightness of capillary permeability. Oc) Pericytes determine blood flow from arterioles to a specific capillary bed. d) When precapillary sphincters constrict, blood flows into metarterioles and then into adjoining capillary beds. e) A microcirculatory bed consists of arterioles, metarterioles, capillaries, and venules.
