Which vessels carry blood away from the heart?

Explanation:
Vessels that carry blood away from the heart are arteries. They start at the heart (left ventricle) and move blood out through the aorta to the body, also including the pulmonary artery that carries blood to the lungs. Arteries have thick, muscular walls with elastic tissue to withstand and regulate the high pressure of blood pumped from the heart. Veins, on the other hand, return blood to the heart and often have valves to prevent backflow. Capillaries are tiny, thin-walled vessels where gas and nutrient exchange occurs between blood and tissues. Nerves are not part of the circulatory system.
