Explanation:
Detailed explanation-1: -veins-these return blood to the heart. capillaries-these are tiny vessels that connect arteries and veins. Their thin walls allow blood to come into close contact with tissues to exchange oxygen, carbon dioxide, nutrients and waste products.
Detailed explanation-2: -Red blood cells pick up oxygen in the lungs. Blood travels away from the heart and lungs through the arteries (ar-tuh-reez). Red blood cells drop off oxygen to the cells through tiny tubes called capillaries (cap-ill-air-ies). Blood then returns to the heart through the veins (vayns) and the cycle begins again.
