D. Nutrients are absorbed and transported to other body parts. The muscular system helps to move food through the digestive system by contracting and relaxing the muscles in the walls of the digestive organs.

The muscles also help to mix food with digestive juices and move it through the small intestine, where nutrients are absorbed and transported to other body parts.
