Explanation:
Detailed explanation-1: -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-2: -As food is digested, blood flows through the capillaries in the intestines. These tubes pick up nutrients. These include glucose (sugar), vitamins, and minerals. These nutrients are sent to the body tissues by the blood.
