What is an artery and what does it do?

Arteries are strong tubes, or vessels, that carry blood from your heart to the rest of your body. Arteries transport blood containing oxygen and nutrients to smaller tubes called arterioles, which then deliver blood to even smaller vessels called capillaries.

What is the structure and function of arteries?

Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins). The primary function of capillaries is the exchange of materials between the blood and tissue cells.
