What are the kidneys?

Comment on this

The kidneys are two organs whose major functions are to remove waste products and excess fluid from the body and produce hormones that regulate blood pressure, red blood cell production, acid regulation and influence calcium, and electrolyte metabolism.

Where are the kidneys located?

The kidneys are bean-shaped organs (about 11 cm x 7cm x 3cm) that are located against the back muscles in the upper abdominal area. They sit opposite each other on both the left and right side of the body; the right kidney, however, sits a little lower than the left to accommodate the size of the liver.

What is the function of the kidneys?

The excess waste products and excess fluid are removed when the kidneys produce urine that is excreted from the body. In addition the kidneys play an important role in regulation of the body salt, potassium, and acid content. The kidneys also produce hormones that stimulate red blood cells to be produced, that help regulate blood pressure and help control calcium and electrolyte metabolism in the body.
