Document Summary
Ureters- carry urine from kidney to urinary bladder. Urethra- tales urine to the outside of the body. Hilum is where the nerves and blood vessels enter the kidney (on most medial surface) Renal artery- deliver blood from heart to kidney. Renal vein delivers blood from kidney to heart. The nephron minor calyces, major calyces, renal pelvis and ureter. Loops of henle do not extend deep into the medulla (85% of our nephrons). Filters the blood/fluid which then enters the proximal convoluted tubule. located near the medulla. Long loops of henle which extend deep into the medulla (15%). arteriole, exits through efferent arteriole. efferent= pressure the endothelial cells of the glomerular capillaries. that wrap around the glomerular capillaries and faciliatete filtration. Simple squamous epithelium becomes cuboidal in pct: visceral layer: )nner layer. Specialised podocytes: fenestrae: window-like openings in, filtrations slits: gaps between, basement membrane: sandwiched, filtration occurs here. the bowman"s capsule into the pct.
