17. Describe how the body systems of this boy function during and after the time he eats his
lunch. Use at least four different body systems
in your answer.

Digestive and muscular systems would be working together to chew food and work it down to the stomach to be digested. The digestive system and circulatory circulatory system would be working together to break food down and move nutrients to cells. The nervous system decides what to eat and when to chew.

when you rub, you also apply pressure, that pressure can urge the poop to come out. i think that when your rubbing, you also might be slightly breaking it up and that can further fill the stomach.
