Question

List the three functions of kidney

Answer 1

Most notably, kidneys remove dangerous toxins and excess water from your blood and eliminate them through your urine. Kidneys also perform other amazing physiological feats, from regulating the amount of fluid in your body to controlling the salt content of that fluid. Here are three more amazing kidney functions.

Answer 2

1. Regulation of extracellular fluid volume. The kidneys work to ensure an adequate quantity of plasma to keep blood flowing to vital organs.

2. Regulation of osmolarity. The kidneys help keep extracellular fluid from becoming too dilute or concentrated with respect to the solutes carried in the fluid.

3. Regulation of ion concentrations. The kidneys are responsible for maintaining relatively constant levels of key ions including sodium, potassium and calcium.
