  1. BLOOD FLOW through the HEART

  2. Biology Version: The right and left sides of the heart work together Right Side Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. Left Side The pulmonary vein empties oxygen-rich blood, from the lungs into the left atrium.

  3. Atrial contraction Right Side Blood flows from your right atrium into your right ventricle through the open tricuspid valve. When the ventricles are full, the tricuspid valve shuts. This prevents blood from flowing backward into the atria while the ventricles contract (squeeze). Left Side Blood flows from your left atrium into your left ventricle through the open mitral valve. When the ventricles are full, the mitral valve shuts. This prevents blood from flowing backward into the atria while the ventricles contract (squeeze).

  4. Ventricular contraction Oxygen and carbon dioxide travels to and from tiny air sacs in the lungs, through the walls of the capillaries, into the blood. Right Side Blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs. Left Side Blood leaves the heart through the aortic valve, into the aorta and to the body. This pattern is repeated, causing blood to flow continuously to the heart, lungs and body.
