PSL300H1 Lecture Notes - Lecture 5: Ace Inhibitor, Aquaporin, Vasoconstriction
Document Summary
Human is 55% water: intracellular fluid 2/3 of human"s water, extracellular fluid: 1/3. Interstitial fluid (b/w cells) 75: plasma 25% Water is most important in the plasma: b/c responsible for distributing nutrient & excreting waste from body. Water can freely move through all 3 compartments (intercellular, extracellular: ex. Na: cannot go into the cells stays in plasma & interstitial fluid, can lead to water movement across the membranes (concentration gradient) Posterior of the body, behind the liver left kidney is higher, b/c right side has the liver. Calyces for collecting urine renal pelvis ureter. Function: take blood, and separate out the nutrients from the waste, and excrete the waste. Will not filter certain larger molecules that the body requires: ex. Hemoglobin, white blood cells, etc: too large to easily be reabsorbed, if body needs to get rid of it, can degrade and recycle. Afferent arteriole glomerulus proximal convoluted tubule loop of. Henle distal convoluted tubule collecting duct.
