Flow of blood through the Heart

Learn how the blood flows through the heart.
Your heart pumps blood throughout your body.
Blood helps keep us alive by transporting oxygen to the cells, removing carbon dioxide, fighting disease, and carrying important nutrients that your body needs.
Your heart has four chambers. Your top chambers are called atriums, and the lower chambers are ventricles.
Blood travels to the lungs by the pulmonary arteries and back to the heart by the pulmonary veins.
