When you eat pizza, it first undergoes mechanical breakdown by your teeth and is mixed with saliva. Once it reaches the stomach, it is churned and mixed with digestive enzymes and gastric acid, which help break down the fats and proteins. Eventually, the remaining waste materials are compacted and prepared for removal from the body.
