The heart has four chambers:

• The right atrium receives serum from the veins and elevates it to the right ventricle.
• The left side atrium carries oxygenated blood from the lungs and elevates it to the left ventricle.

• The left ventricle elevates oxygen-rich serum to the remainder of the body. The left ventricle strong contractions produce our blood pressure.
