Explanation:

The first person to correctly articulate with proof, how the blood circulates the body was William Harvey.

Besides proving that it's the same blood that flows through the veins and arteries, he also showed that Arteries transport oxygenated blood from the heart to the whole body, after the blood has exchanged oxygen for carbon dioxide, the Veins carries the blood without oxygen back to the heart from where it goes to the lungs for more oxygen.
