Document Summary

Filters blood: filters ~200l of fluid/day. Removes waste & toxic products: by producing and excreting urine, excretes ~1. 5l/day. Controls blood composition: excretes excess ions (na, k, ca, etc. , maintains water, electrolyte & ph balance, renin helps maintain blood pressure. Produces hormones & chemicals: erythropoietin: stimulates rbc formation. Anterior: posterior associated with posterior abdominal wall. Margins: medial (green) smaller, located at hilum, lateral (blue) Poles (yellow: superior associated with adrenal glands, inferior. Ivc runs slightly to right: right renal vein is shorter, right renal artery is longer. Right kidney (2. 5cm lower than left: liver. Sits on top, lowers it: duodenum, ascending colon. Left kidney: pancreas, spleen, stomach, jejunum, descending colon. Renal capsule: innermost layer attached to surface, protects kidney. Adipose capsule: protective fatty cushion, also known as perirenal. Renal fascia: dense irregular connective tissue, anchors kidneys and adrenals in abdomen, stops infections of peritoneum into, cortex (outer, blue, medulla (inner, red)
