Document Summary
State the location of the kidneys within the abdominal cavity and in relation to bony landmarks. State the arterial supply, venous drainage of the kidneys. Filters 200 l of fluid/day: excretes approximately 1. 4 l/day as urine. Produce, transport, and store urine: micturition, blood pressure regulation. Kidneys: retroperitoneal structures during development, the kidneys become secondarily retroperitoneal. Located most posteriorly at abdominal wall: behind the small/large intestines stomach and ascending/descending large intestine (intraperitoneal) kidneys & inferior vena cava + aorta. Extends from t12-l3: hilum the area where the renal artery, renal veins, and ureter leave the kidney, the ureter is the most posterior vessel. Processes 20-25% cardiac output: associated adrenal glands are located ontop. Surfaces anterior (renal artery/vein above) & posterior (ureter is above: margins lateral (greater curvature) & medial (lesser curvature) Inferior pole is protected by layers of connective tissue & fat: right kidney.
