What is blood vessels?
Blood vessels are channels that carry blood throughout your body. They help to transport oxygen to vital organs and tissues, and also remove waste products. Blood vessels include veins, arteries and capillaries.
Veins bring blood to the right side of your heart.
Arteries branch into smaller vessels called arterioles. Both arteries and arterioles are very flexible. They get bigger or smaller to help maintain your body's blood pressure.
Capillaries have thin walls that allow oxygen, nutrients, carbon dioxide and waste products to pass through, to and from the tissue cells.
thus, Arterioles are narrow blood vessels that restrict blood flow and Capillaries have thin walls that allow gas exchange.
