Function:
The function of the digestive system is to break down food so it can be used. It also removes solid waste.
Organs:
Some organs include the mouth (for chewing food), the Esophagus (brings food to the stomach), Small Intestines (separates the water from the solids), Large Intestines (squeeze as much liquid as it can until there is no more left), Rectum so it can deposit any thing not absorbed by the body which is considered waste or in other words, poop.
Interactions with Other Systems:
The digestive system works with the circulatory system because of the nutrients absorbed by the digestive system from the food you eat like your daily eggs. It absorbs the food for your body to use but shipped out by the circulatory system to parts of your body. The digestive system also works closely with the endocrine system to control the speed at which digestion goes. And finally it also works with the excretory system though it works parallel with it not with it. But the digestive system collects and removes solids and the excretory system filters compounds from the blood stream and collects them in urine. This is closely working together but not exactly.
Analogy:
Pipes underneath a house are like the digestive system because they take stuff in and it goes where ever it needs to go like your digestive system how it takes stuff in and then it goes where ever it needs to go. The toilet would be the mouth and the pipes would be the intestines and the end of the would thing would be the anus.
Structure and Function:
The stomach is one very important part of your digestive system because it holds the food until it has been broken down in small bits or turning into partly digested mush. Without it there would be big pieces of food clogged in your intestines and you wouldn't be able to digest and have enough energy if you couldn't digest food in stomach. It is like a like bag in your chest but it is like that because it needs space for food to be stored and stay there for a few hours to be digested and then moved into the intestines and then stored in rectum then goes out of the anus. You would need the stomach for digesting all the food that comes in so it can be broken down so you wouldn't have problems every time you eat your sandwich or something.

I think the stomach should be redesigned so it can hold more food and it can break down more food faster so you can eat meals a lot more earlier for people who are always hungry.
