Final answer:
The digestive, cardiovascular, and muscular systems work together to break down food, absorb nutrients, and deliver them to body cells.
Step-by-step explanation:
The digestive, cardiovascular, and muscular systems work together to get nutrients from food to body cells through a series of coordinated processes. Firstly, when food is ingested, it is broken down into smaller molecules by the digestive system. Then, the nutrients are absorbed into the bloodstream through the walls of the small intestine with the help of tiny finger-like projections called villi. These nutrients are then transported to body cells by the cardiovascular system, which uses diffusion to move substances across cell membranes. Finally, the muscular system plays a role in digestion by moving food through the digestive tract via peristalsis, a rhythmic contraction of muscles in the organ walls.
