Anatomy and Cell Biology 3319 Lecture Notes - Lecture 42: Celiac Artery, Ovarian Artery, Proximal Tubule
Document Summary
Functions of the urinary system: filters blood, filters 200 l of fluid/day, excretes approximately 1. 4 l/day, eliminate waste - nitrogenous compounds, excrete excess ions - water/electrolyte balance, produce, transport, and store urine, micturition, blood pressure regulation. Kidneys general: retroperitoneal structures, posteriorabdominal wall: kidneys along this muscular bed, extend from t12-l3, hilum, on the medial surface where the concavity of the c is there is an opening into the kidney. Where vessels go in and out: processes 20-25% cardiac output, surfaces, margins, poles, associated adrenal gland. Removal of intestines can let us see the retroperitoneum: a covering there: by peritoneal covering, duodenum is retroperitoneal. Removal of peritoneal covering = reveal the kidneys. Kidney"s laying on the bed: kidney in relation to vessels, at the top there is a north/superior pole and a south/posterior pole, adrenal gland at the north pole. Hilum: where the artery and vein in and ureter out. View from behind: superior pole is blocked by bony cage.
