How does the digestive system and the muscular system work together?
The smooth muscle in the muscular system helps move food through the intestines in the digestion process. Also the muscles surrounding your stomach assist by churning up food which helps digestion.
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.)
