Document Summary
Ph of the blood 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. In doing so, the 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. It is important to understand that the kidneys do not produce water or electrolytes but only conserve them by reducing the amount removed from the body. They also eliminate waste and foreign substances such as drugs, food additives and vitamins that are excreted in the urine. The kidneys also act as an endocrine gland, producing hormones or components of hormonal systems such as erythropoietin, renin, vitamin d, and stanniocalcin. The kidneys are roughly the size of a fist.
