Document Summary
Kidneys: water balance, electrolyte levels, ph of the blood, long-term regulation of arterial pressure. Remove nonessential substances from the plasma (waste metabolites, excess water, and electrolytes) Play major role in regulating water levels, the chem. conc. of the body fluid compartments, and ph of the blood. Do not produce h2o or electrolytes, but only conserve them. Elimination of waste or foreign subs (drugs, additives, vitamins) Act as endocrine gland: produce hormones or components of hormonal systems (erythropoietin, renin, vitamin d, stanniocalcin) Renal pelvis then drains into the ureter. Inner calyces that drain into a central renal pelvis: nephrons drain through a collecting duct into a calyx. Blood enters through afferent arterioles and is filtered through the glomerulus. Filtrate (h2o and salts) enters the nephron. Filter blood, reabsorb essential substances, and excrete nonessential molecules and waste. Each nephron is composed of a highly coiled hollow tube surrounded by a complex blood supply (peritubular capillary network)
