The pizza is o mechanically broken up by teeth and mixed with saliva.
The waste materials o are compacted and then removed from the body.
The pizza is churned, mixing it
with digestive enzymes and gastric acid.
Enzymes from the liver and pancreas break down fats and proteins in the pizza.

In the stomach, the pizza is first mechanically broken up by teeth and mixed with saliva. Then, it is churned, creating a mixture of digestive enzymes and gastric acid. These enzymes, along with enzymes from the liver and pancreas, break down the fats and proteins in the pizza. Finally, the waste materials are compacted and later removed from the body.
To summarize what happens to the pizza in your stomach, four main processes occur:
1. Mechanical Breakdown: Your teeth chew the pizza, breaking it up into smaller pieces. At the same time, saliva is released, moistening the pizza and making it easier to swallow.
2. Mixing and Churning: Once swallowed, the pizza enters the stomach, where it is mixed and churned with digestive enzymes and gastric acid. This process helps to further break down the pizza and mix it with the digestive juices.
3. Enzymatic Breakdown: Enzymes from the liver and pancreas are released into the stomach and small intestine. These enzymes, specifically lipase and protease, break down fats and proteins present in the pizza, respectively, into smaller molecules that can be absorbed into the bloodstream.
4. Waste Removal: Once the pizza has been broken down and digested, the remaining waste materials are compacted in the large intestine and then eliminated from the body through the process of defecation.
So, to summarize, the pizza undergoes mechanical breakdown, mixing with digestive enzymes and gastric acid, enzymatic breakdown of fats and proteins, and waste removal in the digestive system.
