The digestive system is the system that breaks down food and absorbs water and turns that food into nutrients and gets rid of bacteria in the water.

your stomach and esophagus need eachother as you esophagus is the part of your digestive system that the food goes down it and into your stomach then your stomach digests all of the food and absorbs nutrients and gives them to your body.

The large and small intestine in your body are part of the digestive system and they absorb any water that goes though and then the liver cleans out the bacterial water from the clean water and the bacterial water is your pee while the other water is absorbed into your body.
