Document Summary
Acids (excretes hydrogen ions: hormones, renin: enzyme important in adjusting blood pressure, erythropoietin: hormone that stimulates the red blood cell production in bone marrow. Female urinary system the bladder female repro organs are behind peeing= urination or voiding. Blood enters kidneys through the right anf left renal arteries. No urine formation happens outside the medulla or the cortex. The top of bowmans capsule was ripped away so you can see inside, looking down the very first part of the renal tubules. Glomerulus and bowman capsule: blood (plasma!!) passes through glomeruli, bowman capsule surrounds each glomerulus, renal tubule (pct) is attached to each bowman capsule, proximal convoluted tubule, afferent arrives, efferent exits. Blood supply: renal artery interlobar artery afferent arteriole glomerulus efferent arteriole peritubular capillaries (vasa recta) interlobar vein renal vein. All the little tubes contain blood, peritubular capillaries in response to sodium concentration juxtaglomerular axia. Restriction of arterioles to increase overall blood pressure.
