WORLD HISTORY

Detailed explanation-1: -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.

Detailed explanation-2: -William Harvey, (born April 1, 1578, Folkestone, Kent, England-died June 3, 1657, London), English physician who was the first to recognize the full circulation of the blood in the human body and to provide experiments and arguments to support this idea.

Detailed explanation-3: -Systemic circulation carries oxygenated blood from the left ventricle, through the arteries, to the capillaries in the tissues of the body. From the tissue capillaries, the deoxygenated blood returns through a system of veins to the right atrium of the heart.

Detailed explanation-4: -The blood enters the heart’s right atrium and is pumped to your right ventricle, which in turn pumps the blood to your lungs. The pulmonary artery then carries the oxygen-poor blood from your heart to the lungs. Your lungs add oxygen to your blood.
