Arteries, Arterioles, and Capillaries. The blood vessels in the body look like tubes. As they get farther from the heart and closer to the muscle tissue, they get smaller and smaller in diameter.

Other large arteries branch from the aorta, and those large arteries split into other arteries, which then branch into smaller vessels called arterioles and finally into very fine vessels called capillaries that are right inside the muscle fibers.
