what blood vessel brings blood to the kidneys
In Depth: Vessels. The kidneys are important to the bodyâs production of urine, but they also play a role in regulating important components of the blood. Blood comes to the kidneys from the abdominal aorta and inferior vena cava, the large arteries and veins that are part of the ascending aorta. Oxygenated blood is brought to the kidneys from a small branch called the renal artery.
