Definition
A kidney is an organ in the body that filters waste from the blood and helps produce urine.
A kidney is one of two bean-shaped organs located toward the back of the abdomen. It cleans the blood by removing waste products and extra water, which leave the body as urine. Kidneys also help control the body’s balance of fluids and salts. People often use the word in health and anatomy contexts.
Examples

Common mistake
Learners sometimes confuse kidney with liver, but kidneys are a pair of organs that filter blood and make urine, while the liver has different functions.
