The arteries have thick elastic walls without valves inside, blood flows under high pressure and carries blood away from the heart to different parts of the body.Arteries are blood vessels that carry blood away from the heart to other tissues. The arteries are the first blood vessels that the heart pumps blood through, they experience the highest blood pressure, so they have thick elastic walls to withstand the high pressure. These large arteries expand when the pressure of the blood rises and then recoil when the heart relaxes between beats to provide a smooth flow of blood through your body.
