1 - Oxygen-poor blood (shown in blue) flows from the body into the right atrium.
2 - Blood flows through the right atrium into the right ventricle.
3 - The right ventricle pumps the blood to the lungs, where the blood releases waste gases and picks up oxygen.
4 - The newly oxygen-rich blood (shown in red) returns to the heart and enters the left atrium.
5 - Blood flows through the left atrium into the left ventricle.
6 - The left ventricle pumps the oxygen-rich blood to all parts of the body.
