Document Summary
List and describe the 7 major functions of the kidney. Regulation of extracellular fluid volume (ecf) & blood pressure: kidney works very closely with the heart. Regulation of osmolarity: kid(cid:374)eys (cid:373)ake sure os(cid:373)olarity is appropriate so (cid:272)ells do(cid:374)"t (cid:271)urst or shri(cid:448)el. Maintenance of ion balance: kidneys maintain salty banana: when sodium levels increase after you eat, your kidney gets rid of the extra sodium. If you do(cid:374)"t ha(cid:448)e e(cid:374)ough io(cid:374)s, the kid(cid:374)ey (cid:449)ill try to (cid:272)o(cid:374)ser(cid:448)e the(cid:373) Maintenance of body ph: kidneys work closely with lungs to maintain ph: there is a very narrow range that is considered physiologically safe. Excretion of waste: kidney puts ingested or produced waste into urine to be excreted (e. g. urea, ammonia, creatinine) Production of hormones: kidney produces and activates hormones: erythropoietin important for the formation of red blood cells, vitamin d not produced in the kidney, but activated, makes us happy and helps with calcium absorption.
