What blood vessel does blood go through to the kidneys? It goes through the renal artery. Oxygenated blood, rich in oxygen, that is part of the circulatory system for the main aorta, it's already been through the pulmonary artery. It goes to the lungs for oxygenation. As we remember that when you get to the lungs, that's where the air from where we breathe goes in at the alveoli and with the capillary bed, it exchanges the oxygen and the carbon dioxide and that's part of the waste and it's breathed back out again. And that's where that exchange takes place. Then, at that point, it goes on to the pulmonary veins. Now, the pulmonary veins is the only vein in the body that has oxygenated blood. So, it seems strange there, but that's the way the system is set up. The pulmonary vein takes the oxygenated blood to the left side of the heart. Then, from the left side of the heart, it goes to the systemic circulation. From the systemic circulation, it goes to the aorta. Now, then it goes to the renal artery. So, there you have the blood vessel that where the blood goes through to the kidneys and, again, it's through the renal artery.
