Blood Vessels Anatomy Coloring Page and Activity Template

3 types of blood vessels - artery, vein, capillary

Did you know that you have 60,000 miles of blood vessels? Blood vessels are basically like tunnels or tubes. Your amazing body has 3 types of vessels that carry blood to different parts of your body: arteries, veins, and capillaries.

3 Types of Blood Vessels

  • Arteries are the thickest type of blood vessel. These blood vessels carry blood from the heart to other parts of the body. Because arteries have lots of fresh oxygen, they are usually shown as red squiggly lines on human body diagrams.
  • Veins are slightly thinner than arteries. These blood vessels carry blood from parts of the body back to the heart. Because veins have less oxygen, they are usually shown as blue squiggly lines on human body diagrams.
  • Capillaries are the tiniest blood vessels with very thin walls. Because these blood vessels connect arteries and veins, they are usually shown as purple squiggly lines on human body diagrams.
