    Chambers of the Heart

    h9991324_001.jpg

    The heart has four chambers: two atria and two ventricles.

    • The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.
    • The right ventricle pumps the oxygen-poor blood to the lungs.
    • The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.
    • The left ventricle pumps the oxygen-rich blood to the body.
