Blood Flow in Human HeartDay and night, the muscles of your heart contract and relax to pump blood throughout your body. When blood returns to the heart, it follows a complicated pathway. If you were in the bloodstream, you would follow the steps below one by one.

  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 from the left atrium into the left ventricle.
  6. The left ventricle pumps the oxygen-rich blood to all parts of the body.
