- - - - The right side pumps blood to the lung
      - Heart pumps blood around the body
      - The left sides pumps blood to the rest of the body
    - - The wall of the left ventricle is much thicker than the right ventricle
      - Needs to build up enough pressure to move the blood to all the main organs
    - - 4 chambers
      - Cardiac muscle
      - Right atria, ventricle - receives deoxygenated from body
      - Left atria , ventricle - receives oxygenated from lungs
      - Pulmonary arteries
        
        carry deoxygenated blood away from heart to the lungs
        
        Unusual as arteries carry oxygenated blood
    - - large blood vessels that carry blood from the lungs to the left atrium of the heart and then get transported to the body
      - They carry oxygenated blood
      - Unusual since almost all other vein carry deoxygenated blood.
  - - - Blood in the right ventricle is pumped to the lungs
      - blood from the lungs flows back into the left atrium and then into the left ventricle.
      - Blood in the left ventricle is pumped to the rest of the body through the aorta
      - Blood returns to the heart where it enters the right atrium.
    - - made with cardiac muscle
      - Constantly active
      - needs its own blood supply through the coronary artery , it provides with oxygen and glucose.
    - - Working of the valves
        Valves in the heart prevent blood from being pushed backwards up into the atria when the heart ‘beats’.
