Journey of Blood

• Blood Enters the Right Atrium from the body with
  Carbon Dioxide (waste products) and without
  Oxygen
• The Right Ventricle pumps blood through Pulmonary
  Artery to the Lungs
• In the Lungs the Blood Dumps the Carbon Dioxide
  and Picks Up Oxygen
• Blood Returns to the Left Atrium through the
  Pulmonary Vein
• The Left Ventricle Pumps the blood to the rest of
  the Body through the Aorta
