How it works:

  1. Right Side (Blue): Blood enters from the body via the Vena Cava into the Right Atrium. It moves to the Right Ventricle and is pumped to the Lungs via the Pulmonary Artery.
  2. Left Side (Red): Blood enters from the lungs via the Pulmonary Vein into the Left Atrium. It moves to the Left Ventricle and is pumped to the rest of the body via the Aorta.
