Document Summary
Excrete toxic waste, regulate water balance, maintain acid vase balance, aid in controlling salt concentrations. Filer 200l of blood regulate volume and chemical composition of blood. Produce rennin (blood pressure) + erythropoietin (red blood cell formation) Anchored via fibrous and fatty tissue (from abdominal aorta) renal arteries deliver of total cardiac output to kidneys/ minute veins leaving kidney exit kidney as renal veins enter ivc. Nephrons : (a) a capsule enclosing a glomerulus (a coiled series of small blood capillaries), and (b) an attached renal tubule. Kidneys process 47 gallons of fluid daily (1% exits as urine rest is reused: urine 95% water, 5% solids (organic inorganic materials) Urine = product of filtered & secreted substance. Renal clearance: kidney ability to clear (or cleanse) a given volume of plasma (fluid portion of the blood) of a particular sub stance in a given time, usually 1 minute. Renal clearance tests use gfr to determine glomerular dysfunction or damage.
