What does a kidney do?!


Question: The kidneys regulate the body's fluid volume, mineral composition and acidity by excreting and reabsorbing water and inorganic electrolytes. This helps balance these substances (which include sodium, potassium, chloride, calcium, magnesium, sulfate, phosphate and hydrogen) in the body and keep their normal concentrations in the extracellular fluid. Body fluid volumes, which are regulated by the kidneys, are related to blood volume and the blood pressure in your arteries.

Their primary role is to maintain the homeostatic balance of bodily fluids. They primarily do this by filtering and secreting metabolites (such as urea) and minerals from the blood and excreting them, along with water, as urine.

I'm not entirely sure...but they hurt like hell if they get punched.

They cleanse the blood of toxins. That's why when they quit working a person has to be put on dialysis, a machine that works similar to kidneys.

Hope this helps.
