What is the main role of arteries?

Explanation:
Arteries carry blood away from the heart to the rest of the body. Their thick, muscular walls withstand the high pressure generated when the heart pumps, helping push blood through the systemic circulation. This is different from veins, which return blood to the heart at lower pressure and with valves to prevent backflow. Gas exchange happens primarily in the lungs via the pulmonary capillaries, not in arteries. So the main role of arteries is to take blood from the heart out to the body.
