Arteries and veins :
- Arteries and veins are two types of blood vessels in the circulatory system that are primarily responsible for circulating blood throughout the body.
- However, the two blood vessels function very differently from one another.
- Arteries are blood vessels that transport blood away from the heart and into smaller vessels.
- Veins are blood vessels that run throughout the body and carry blood towards the heart.
Final answer: Arteries carry oxygen-rich blood from the heart to all parts of the body and veins carry carbon dioxide-rich blood from all parts of the body back to the heart. Veins have thin walls and arteries have thick elastic walls. Blood flows at high pressure in arteries Valves are present in veins which allow blood to flow only towards the heart. Arteries divide into smaller vessels. These vessels further divide into extremely thin tubes called capillaries. The capillaries join up to form venules.
