  Arteries - Large Blood Vessel that carries blood from heart to your body.This contains oxygen and nutrients. As the blood flows away from heart, the arteries branches.
  Capillaries - Smallest branches are called capillaries. This is where oxygen is transferred to your tissues. It exchanges wastes from cells are transferred into the blood. The capillaries began to merge together and eventually forms larger vessel.
  Veins - The large vessel that are formed from capillaries are called veins. It leads back to the heart. As the deoxygenated blood came in and out of the arteries, it picks up the oxygen and nutrients.
  
  Similarities:
  1. They are all blood vessels.
  2. They are all able to contract and expand soft and fast.
  3. They do not get tired of expanding and contracting, like how muscles get tired of doing it.
  4. They are all linked to the heart.
  
  Differences:
  
  Arteries:
  It has high pressure and no valves.
  Mainly carries oxygenated blood.
  It carries blood away from heart.
  
  Capillaries:
  Smallest blood vessel
  It carries oxygen to the tissues.
  
  Veins:
  It carries blood into the heart
  It has lower pressure
  It has valves
