The renal arteries are blood vessels that supply oxygenated blood to the kidneys. Each kidney has its own renal artery, which branches off from the abdominal aorta. These arteries play a crucial role in filtering blood and maintaining fluid balance in the body. The renal arteries are essential for kidney function, as they deliver the necessary blood flow for the kidneys to filter waste and excess substances. Any blockage or narrowing of these arteries can lead to serious health issues, including hypertension and kidney damage. Proper blood flow through the renal arteries is vital for overall health.
