There are three things that happen to food in the stomach:
Physical digestion
Chemical digestion
Temporary storage of food

The food is broken down into smaller pieces by mechanically 'churning' it. This is done by the muscular wall of the stomach. As it contracts and relaxes, it causes the food particles to break down. This increases the surface area of food so that more surface is available to the enzymes for digestion and thus, the rate of digestion is faster. This is the physical digestion that happens in the stomach.

The stomach also releases gastric juices into the food. These are also thoroughly mixed with the food particles by the churning movement of the stomach wall. These gastric juices contain pepsinogen which is activated by the hydrochloric acid present in the stomach to pepsin. Pepsin is a protease and helps in breaking down proteins into amino acids. Thus, stomach is also the site for protein digestion. This is how stomach brings about chemical digestion./

After the food is thoroughly mixed and churned, the result is a liquid mixture called 'chyme'. Chyme is then released into the small intestine in short bursts. It may be temporarily stored in the stomach as the amount that has passed on to the small intestines is being digested.

The stomach also absorbs some food stuffs through its walls and into thee blood stream like alcohol, aspirin and glucose.

It churns with some strong acid and stays in the stomach for 4 hours...that's why we often get hungry atrer 4 hours because our stomach is empty and is saying "feed me feed me!"
(no it's not but you know what I mean) people who loose energy quicker will get hungry in matbe an hour or 2... That's what happens to the food in our stomach!

It is basically just a place for storage, some enzymes are present in there which are called protease and they work on proteins then it just continues its path down through the pyloric sphincter and into the top of the small intestine called the duodenum

Either it dissolves and gets digested or is excreted as excess
