The pizza that you ate for lunch goes through several processes in your stomach. First, it is mechanically broken up by your teeth and mixed with saliva as you chew. Then, the pizza enters your stomach where it is churned, mixing it with digestive enzymes and gastric acid. Next, enzymes from the liver and pancreas break down the fats and proteins in the pizza. Finally, the waste materials from the pizza are compacted and then removed from the body.
The correct answer is: The pizza is mechanically broken up by teeth and mixed with saliva.
To summarize what happens to the pizza in the stomach, we need to understand the process of digestion.
When you eat the pizza, it enters your mouth where it is mechanically broken up by your teeth and mixed with saliva. The saliva contains enzymes that start breaking down carbohydrates in the food.
Next, the pizza travels down the esophagus and into the stomach. In the stomach, the pizza is further broken down by churning and mixing it with digestive enzymes and gastric acid. This process helps to break down proteins and fats in the food.
After the pizza has been sufficiently broken down, it moves into the small intestine. Here, enzymes from the liver and pancreas break down fats and proteins present in the pizza.
Finally, the waste materials, which are the undigested parts of the pizza and other food components, are compacted in the large intestine and then removed from the body as feces during the process of defecation.
So, summarizing what happens in the stomach, the correct answer is that the pizza is mechanically broken up by teeth and mixed with saliva.
