The kidneys are two organs in the abdomen of vertebrates which are shaped like beans. They regulate the amount of water and salts in the blood. They make urine so it can be removed from the body.
The adjective which is used for kidneys is renal. For example, renal failure is when the kidneys are sick and do not work.
The prefix nephro- is also used in words to mean "kidneys". For example, a nephrologist is a specialist who studies kidneys.
