  • Blood vessels make up your overall blood circulatory system
  • Arteries carry blood away from the heart
  • veins carry oxygenated blood to your heart
as blood is pumped away from your heart , it travels through aorta to arteries ,ateroles and the capillary. Blood flow through the capillary beds reaches almost every cell in the body and is controlled to move blood according to the body needs. After oxygen is moved away from the blood deoxygenated blood flows to the lungs where it is reoxegenated and sent back to the heart to start over.
