What blood vessels carry blood to arms? The aorta, the largest blood vessel in the body is oxygenated blood and it actually takes all the blood to all the areas with oxygenated blood. There's some backup information that might be interesting to you, that de-oxygenated blood which we sometimes refer to as blue blood because it doesn't have the hemoglobin and the oxygen attachment which makes it red. The de-oxygenated blood goes to the right side of the heart and then the same de-oxygenated blood goes to the pulmonary artery and then it goes to the lungs, to the capillary bed, with the alveoli, so that it can become exchanged with oxygen and the nutrients, and exchanged for the waste and the carbon dioxide. Then it goes to the pulmonary veins and to the left side of the heart. After it gets to the left side of the heart, it goes to the aorta, to the head, the arms, the legs and the organs. So, the aorta is the one that takes the blood vessels to the arms.
