Document Summary
Functions of the urinary system: filters blood, filters 200 l of fluid/day, excretes approximately 1. 4 l/day, produce, transport, and store urine micturition, blood pressure regulation, eliminate waste nitrogenous compounds, excrete excess ions water/electrolyte balance. Just like in the lungs when we looked at the mediastinal surface and saw where bronchi and blood vessels went in: processes 20-25% cardiac output. If you remove this covering, can see the kidneys: hard to get to the kidneys bc you have to go through all these layers of structures. Kidney anatomy: north/superior pole associated w adrenal gland. Hilum renal artery, renal vein and ureter (most posterior) Where the renal artery and vein travel into the kidney and where the ureter travels out of kidney. Surfaces: anterior surface, removed peritoneal covering to see surface bc kidneys are retroperitoneal, posterior surface, margins, lateral margin, medial margin, think of these margins like the stomach: lesser and greater curvature, poles, superior pole adrenal gland.
