Which part of heart contains pure blood?
The left half of the heart collects and pumps pure (oxygenated) blood from the lungs to all parts of the body. The blood from the lungs enters the heart from four veins called the Pulmonary Veins. These veins bring the blood into the left upper chamber called the Left Atrium.
How did Harvey prove Galen wrong?
His strongest evidence was that it would be impossible for the body to replenish the amount of blood it would consume under Galen’s theories. He arrived at this conclusion by calculating the total volume of blood that moves through the body in an hour and showed that it was too high for the body to replenish.

How did William Harvey find out about the blood circulation?
Harvey also proved that blood flows in two separate loops, the pulmonary circulation and the systemic circulation. He then tied a ligature on the upper arm of a person, which distended the veins in the forearm and made the valves of the forearm clearly visible.
