Principal Blood Vessels of the Heart

Principal blood vessels of the heart:

  • Arteries – carry blood away from the heart and generally carry oxygenated blood.
  • Aorta – carries oxygenated blood from the heart to most of the body.
  • Coronary Artery – carries oxygenated blood from the heart to the heart tissue.
  • Pulmonary Artery – carries de-oxygenated blood from the heart to the lungs. The pulmonary artery is the only artery in the body that transports de-oxygenated blood.
  • Veins – carry bloods towards the heart and generally carry de-oxygenate blood.
  • Superior Vena Cava – carries de-oxygenated blood from most of the body above the diaphragm, except the alveoli and heart, to the heart.
  • Inferior Vena Cava – carries blood from the lower and middle body into the right atrium of the heart.
  • Coronary Sinus – carries de-oxygenate blood from the heart tissue to the heart.
  • Pulmonary Vein – carries oxygenated blood from the lungs to the heart. The pulmonary vein is the only vein in the body that transports oxygenated bloods.
