Circulatory System - Blood Vessels

There are three types of blood vessel:

  • ARTERIES - these carry the blood away from the heart
  • CAPPILLARIES - these are involved in the exchanging if materials at the tissues (really tiny)
  • VIENS - these carry the blood to the heart

The Arteries:

They leave the heart and carry blood away from it. The heart pumps blood at high pressure and enters the artieries so they have:

  • Strong walls - elastic fibres allow them to move to stretch and then recoil at every blood spurt
  • Contain a thick layer of muscle…
