muscular System
Other systems that work with the muscular system are the skeletal system. & the digestive system.
MUSCULAR
The muscular system is the mechanical force behind the digestive system. Beginning when you take a bite, your muscular system aids your digestive system. Chewing and swallowing are done by the muscular system; muscles surrounding your stomach churn up food to aid digestion; muscles transport digested food through your intestines and eventually out of your body. (The muscles for chewing and swallowing are voluntary muscles; the rest are involuntary.)
actually the skeletal system and nervous system work with the digestive system
i think endocrine
The muscular system is needed in the digestive system because the food (or other objects entered through the mouth) needs to be pushed through the system somehow.
