Explanation:

Detailed explanation-1: -The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

Detailed explanation-2: -The circulatory system consists of the heart, capillaries, arteries and veins. While arteries carry blood away from the heart, the veins (in most cases) carry blood back to the heart. The capillaries facilitate the exchange of oxygen and nutrients to the cells.

Detailed explanation-3: -Your heart is the only circulatory system organ. Blood goes from the heart to the lungs to get oxygen. The lungs are part of the respiratory system. Your heart then pumps oxygenated blood through arteries to the rest of the body.
