These thick walled blood vessels carry oxvgenated blood to the cells in your body?

The thick-walled blood vessels that carry oxygenated blood to the cells in your body are called arteries. They transport oxygen-rich blood away from the heart, with the aorta being the largest artery. The walls of arteries are muscular and elastic, allowing them to withstand and regulate the high pressure of blood pumped from the heart. As arteries branch into smaller arterioles and capillaries, they deliver oxygen and nutrients to tissues throughout the body.
