Many substances need to be transported around the body. Nutrients are transported from organs to the individual cells where they are used. Wastes are transported from the body cells to the organs where they are expelled out of the body. Mammals have circulatory systems for the movement of substances in the body. Metabolic processes are facilitated through the circulating system.
