Explanation:
Detailed explanation-1: -Capillaries complete the circulatory system by connecting arteries to veins: Arteries carry oxygen-rich blood from the heart to your organs.
Detailed explanation-2: -As blood moves through the capillaries, the oxygen and other nutrients move out into the cells. Then waste matter from the cells goes into the capillaries. As the blood leaves the capillaries, it moves through the veins. Veins merge into larger tubes to carry the blood back to the heart.
Detailed explanation-3: -Capillaries are small, thin blood vessels that connect the arteries and the veins. Their thin walls allow oxygen, nutrients, carbon dioxide and waste products to pass to and from the tissue cells.
