Document Summary
Unit 1: cardiovascular physiology (k: lymphatic vessels: Removal of lymph node (fluids cannot be reabsorbed in that localized area) Increased bp creates edema because not enough materials can be absorbed. Heart failure: heart doesn"t have the ability to pump the blood so the blood pools in the veins and capillaries: decreased net pi. Decreased plasms protein production in the liver decreases pic (so blood osmotic pressure is reduced) Sometimes increased proteins cause the kidneys to push proteins through the capillary (proteinuria) less plasma proteins = pic goes down = fluids accumulate in tissue = edema. Increasing pulse pressure (systole-diastole) = increased firing rate. Impacts heart and blood vessels (depends on the pathway used: long term regulation, works by controlling blood volume, affects venous pressure and return, which affects edv, which affects esv and co, hormones from brain, kidney and heart. Antidiuretic hormone = brain (vasoconstriction = reduces release of water)
