What kind of blood do arteries carry?

Arteries carry arterial blood away from the heart through the aorta and carotid arteries. Venous blood is then circulated back to one of the vena cavas where it enters the right atrium, go's through the tricuspid valve into the right ventricle so that it can be taken through the pulmonary valves to t

he lungs. There, it once again becomes arterial blood, and is taken through the left chambers to the aortic arch and the cycle repeats.
