What is the function of kidneys?
1 Answer | add yours
The kidneys are part of the human renal or urinary system, and serve primarily to filter toxins out of the blood while producing urine. In addition to filtering out toxins, the kidneys also help remove urea, another form of waste that results from the process of metabolizing protein, which is a product of the liver. The urea that is produced by the liver’s function is filtered out of the blood stream by the kidneys, and is then expelled in urine. Another function of the kidneys is to help the body retain enough fluids to stave off dehydration. As the body reacts to a shortage of water, the kidney’s cease producing urine in order to retain what moisture remains in the blood system. In addition, kidneys produce erythropoietin, a hormone vital to red cell production, when they detect a shortage of oxygen.
Human anatomy includes two kidneys, although only one is vital to survival. That duplication makes possible the donation of healthy kidneys to individuals suffering from renal failure and requiring a kidney transplant.
