Heart

• Aorta


  The largest artery in the body, carrying oxygen-rich blood from the heart to the rest of the body
• Mitral valve

  A valve that allows blood to only move in one direction
• Right atrium


  The upper right chamber of the heart
• Tricuspid valve

  A valve that allows blood to only move in one direction
• Inferior vena cava


  One of the two large veins that lead to the heart
• Pulmonary valve


  A valve that allows blood to only move in one direction
• Right ventricle


  The lower right chamber of the heart
• Superior vena cava


  One of the two large veins that lead to the heart
• Pulmonary artery

  A blood vessel that carries blood from the heart to the lungs
• Left atrium

  The upper left chamber of the heart
• Left ventricle

  The lower left chamber of the heart
• Pulmonary vein

  A blood vessel that carries oxygen-rich blood from the lungs to the heart
• Blood in the pulmonary vein is oxygen-rich
• Blood in the superior and inferior vena cava is less oxygen-rich
• Blood in the aorta is oxygen-rich
• Blood in the pulmonary artery is less oxygen-rich
• The heart pumps blood through the aorta to the rest of the body
• The heart pumps blood through the pulmonary artery to the lungs
• Oxygen and waste gases are exchanged in the lungs through diffusion
