answer
You will probably recognize the main arteries in the human body:
  • the aorta the main artery coming out of the heart
  • coronary arteries in the heart
  • the carotid artery in the neck.
However, there are more than 20 major arteries throughout the body, which then branch out into many, many smaller arterioles and capillaries. This extensive network carries blood to all parts of the body.

Each artery is made up of three layers:
  • a smooth layer on the inside
  • a thick layer of muscle in the middle
  • a rough layer on the outside.
