Document Summary

Renal system includes the kidneys, ureters, bladder, and urethra. Principal function of the kidneys is the regulation of water balance, electrolyte levels, ph of the blood, and the long-term regulation of arterial pressure. Basic function of the kidneys is to remove nonessential substances from the plasma, including waste metabolites, excess water, and electrolytes and to recover any essential substance like glucose. Kidneys play a major role in regulating the water levels, the chemical concentration of the body fluid compartments, and ph (or acidity) of the blood. Kidneys do not produce water or electrolytes but only conserve them by reducing the amount removed from the body. The elimination of waste or foreign substances is an important function of the kidneys. The kidneys also act as an endocrine gland, producing hormones or components of. Includes the removal of drugs, food additives, and vitamins that are excreted in the urine. hormonal systems such as erythropoietin, renin, vitamin d, and stanniocalcin.
