Our kidneys perform 3 basic functions:
Eliminate via the passing of urine the waste products of metabolism or functioning of the body. In other words, eliminate toxic substances such as urea and creatinine that the body no longer needs.
Regulate the balance between sodium and water in the body and control the concentration of many other salts such as potassium, calcium, phosphorus and magnesium among others; make the urine more concentrated (has more color because it has less water) or more diluted (less color, because it has more water). The kidneys also remove the acidic that are formed from the decomposition of the nutrients in this way control the acidity of the body.
The kidneys produce a hormone with various tasks. Three of the functions of these hormones are: Through the kidney renin helps control blood pressure. The kidneys also secrete erythropoietin, the hormone responsible for stimulating production of red blood cells, so the decrease or absence of this hormone inevitably causes anemia. In the kidney, which is activated vitamin D, which allows the absorption of calcium and phosphorus in the intestine, which is necessary for bone mineralization.
