blood vessels

Front 24

An __ is a blood vessel that carries blood away from the heart. These blood vessels have thick muscular walls & they divide into smaller & smalled branches which carry the blood to the body's organs.

Back 24

artery

Front 25

The smallest vessels are called __. These blood vessels are so small that the blood cells move through them in single file.
