The renal veins are the blood vessels that carry deoxygenated blood from the kidneys back to the heart. In the human body, there are typically two renal veins, one for each kidney. They play a crucial role in the filtration and removal of waste products from the blood, helping maintain the body's fluid and electrolyte balance. The renal veins are essential for the proper functioning of the kidneys and overall circulatory system.
