Main Blood Vessels in the Body

  • Blood is carried away from the heart and towards organs in arteries
  • These narrow to arterioles and then capillaries as they pass through the organ
  • The capillaries widen to venules and finally veins as they move away from the organs
  • Veins carry blood back toward the heart
