Document Summary
Renal anatomy: cortex: looks granulated = tubules + renal corpuscle, medulla: striated = loop of henle, calyces renal pelvis ureter, renal pelvis: where urine is collected, ureter: urine goes out of kidney toward the bladder. Kidney blood supply: liver and kidney get the most blood flow in the body (1500 and 1260 ml/min, respectively, however, the kidney has much smaller mass than the liver so it has higher blood flow. 4200 ml/min/kg than the liver (577 ml/min/kg): kidney makes up < 0. 5% of the mass of the whole body, but receives 20% of the total cardiac output in a day. The nephron: the nephron is the functional unit of the kidney. Similarity: both have rc in the cortex layer. Cortical nephrons: more abundant 80: corpuscle sits inside the cortex, short loh, peritubular capillaries: much more twisted reabsorption of substances from the tubules.
