What is Kidney?

Kidney

Quick Answer

A kidney is a vital organ in the body that filters waste products from the blood and produces urine. It helps maintain the body's fluid balance, electrolyte levels, and blood pressure.

Overview

The kidneys are two bean-shaped organs located on either side of the spine, just below the rib cage. They play a crucial role in filtering blood, removing waste, and balancing fluids and electrolytes. Each kidney contains about a million tiny filtering units called nephrons, which are responsible for this essential work. When blood flows into the kidneys, the nephrons filter out waste products and excess substances, which are then excreted as urine. This process also helps regulate important minerals like sodium and potassium, ensuring that the body maintains a healthy balance. For example, if you consume too much salt, the kidneys will work harder to remove the excess sodium from your body. The health of your kidneys is vital for overall well-being. If the kidneys fail to function properly, waste can build up in the body, leading to serious health issues. Regular check-ups and staying hydrated can help keep the kidneys healthy, highlighting their importance in the anatomy and physiology of the human body.
