Document Summary
Renal system: includes kidneys, ureters, bladder, urethra: principal functions: water balance, electrolyte levels, ph of the blood, long-term regulation of arterial pressure. Basic function: to remove nonessential substances from the plasma, and recover essential substances such as glucose: remove: waste metabolites, excess water, electrolytes, drugs, food additives, vitamins. The kidney does not produce water or electrolytes - just conserves them by reducing the amount removed from the body. Kidney can act as an endocrine gland. Calyces: composed of collecting ducts from many nephrons, drain into a central renal pelvis. Renal artery: major source of blood to the kidney. Interlobar arteries: branches from the renal artery. Interlobular arteries: branches off arcuate arteries, supplies the nephron. Interlobular vein: collects blood from the nephrons. Arcuate vein: collects blood from interlobular veins. Interlobar vein: collects blood from arcuate veins. Renal vein: collects blood from interlobar veins. Renal corpuscle: the glomerulus + bowman"s capsule. The interlobular artery drains into the afferent arteriole.
