Artery, Vein, Capillaries Anatomy diagram labeled facts
  • ARTERIES are the biggest blood vessels. They carry blood from the heart to other parts of the body. Because arteries carry fresh oxygen, they are usually red in anatomy diagrams.
  • VEINS are slightly thinner than arteries. They carry blood from all over the body back to the heart. Because veins have less oxygen, they are usually blue in anatomy diagrams.
  • CAPILLARIES are the smallest blood vessels with fragile walls. Because they connect arteries and veins, they are usually purple in anatomy diagrams.

The wrist is an easy area to check the pulse in 3 steps:

  1. Press two fingers on the side of your wrist (under your thumb).
