In Depth: Vessels. The kidneys are important to the bodyâs 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.
Arteries and veins carry blood around your body. Arteries take blood away from your heart, delivering it to your organs and muscles. Veins bring blood back to your heart from those same organs and muscles. Your main arteries include the coronary arteries of your heart, the carotid and cerebral arteries of your brain, and the peripheral arteries, which stretch out into your limbs.
