Kidneys are the principal excretive organs Not only excrete waste metabolic products to remove various harmful substances But also regulate a variety of material in plasma to maintain the homeostasis of internal environment (osmolality and acid-base balance Besides, kidneys also produce some bioactive substances renin, prostaglandins(regulation of blood pressure erythropoietin(formation of matured RBCs)

The following pathologic process is termed"renal failure": Various causes Severely impair renal function Glomerular filteration rate Retention of metabolic wastes Disturbanc of internal environment a serial of clinical manifestations Renal failure Acute renal failure(arF (CRF) Cronic renal failure Uremia
