Main function
This system lets us digest our food so then we don't get to many pieces of food in our body's. Organs and parts in this system are the small and large intestine, mouth, and the throat. This system also works with the nervous, muscular, and circulatory systems.
The way this system works with the nervous system is the nerves "tell" the food and liquid were to go. fun facts. Food stays in our stomachs for 2 to 3 hours. We make 1 to 2 pints of saliva a day.
