Three types of blood vessels .

• Arteries
• Veins
• Caterpillars (I mean
  capillaries)

Arteries carry blood away from the heart.

Veins carry the blood back to the heart
13
Capillaries are tiny tubes that carry blood
from the arteries to the bodys cells, from the
cells to the veins.

As blood moves through your body it exerts
pressure against the walls of blood vessels.
This is known as
Blood pressure
