  • The pulmonary artery goes away from the heart, to the lungs, carrying deoxygenated blood
  • The pulmonary vein goes from the lungs to the heart carrying oxygenated blood
  • The arteries generally go away from the heart carrying oxygenated blood to the other body parts (apart from pulmonary artery)
  • The veins generally go to the heart from the organs carrying deoxygenated blood (apart from pulmonary vein)
  • The hepatic artery goes to the liver. The hepatic vein goes away from the liver.
  • The hepatic portal vein goes away from the gut to the liver
  • The renal artery goes to the kidneys. The renal vein goes away from the kidneys.
  • The vena cava is the main vein going to the heart

  • Blood transports respiratory gases, metabolic waste, products of digestion and hormones around the body
