MICROANATOMY

Detailed explanation-1: -The blood circulatory system (cardiovascular system) delivers nutrients and oxygen to all cells in the body. It consists of the heart and the blood vessels running through the entire body. The arteries carry blood away from the heart; the veins carry it back to the heart.

Detailed explanation-2: -The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.

Detailed explanation-3: -Your circulatory system, which consists of your heart, blood and blood vessels, are responsible for transporting nutrients to the cells of your body. Specifically, nutrients are transported throughout your body through your blood via capillaries, tiny blood vessels that connect arteries to veins.
