(2) stimulates the release of renin, which restricts losses of water and salt in the urine through reabsorption at the nephron. The main purpose of the kidneys is to separate urea, mineral salts, toxins, and other waste products from the blood. In addition, the kidneys also conserve water, salts, and electrolytes.
The kidneys are an essential part of the urinary system and also serve homeostatic reasons such as the regulation of blood pressure and acid-base balance. They take out waste such as urea and ammonium; also responsible for reabsorpitation of water, glucose, and ammonium acid. Filtering out wastes to be excreted in the urine. 2  Regulating blood pressure via both urinary excretion of wastes and initiating the renin-angiotensen hormone regulatory system. 3  Regulating an acid-base balance via the bicarbonate system. 4  Stimulating red blood cell production via the release of the hormone erythropoietin.
