Document Summary
Blood distribution: at rest, a large portion of blood is in systemic veins & venules as they are blood reservoirs (64% of blood in veins & venules) Larger size of molecules move depending on type of capillary. Dynamics of capillary exchange what movement net out of capillary & net movement into capillary is important: filtration is pressure-driven movement of. Interstitial fluid osmotic pressure (ifop) promote ltration: reabsorption is pressure-driven movement of uid from interstitial uid to capillaries. Interstitial fluid hydrostatic pressure (ifhp) & blood colloid osmotic pressure (bcop) promote reabsorption. Vascular resistance (r) the opposition of blood ow due to friction between blood & walls of blood vessels: resistance depends on: 1) size of blood vessel lumen 2) blood viscosity 3) total. Venous return volume of blood owing back through systemic veins, occurs due to pressure generated by contractions of heart"s left ventricle: venous return is assister by:
