What is the name of the part of the digestive system that breaks down food?
The digestive system helps the body break down food into energy and nutrients. It consists of organs such as the mouth, esophagus, stomach, small intestine, large intestine, and rectum. Food passes through the digestive system, which helps turn it into energy and waste.
The Digestive System
Consists of primary organs and secondary organs Primary organs are those that the food travels through (mouth, esophagus, stomach, small intestine, large intestine, rectum) Secondary organs supply enzymes to help the food digest (liver, pancreas, gallbladder)
Amylase - found in saliva, starts the breakdown of carbohydrates in the mouth Pepsin - breaks down proteins in the stomach Lipase - made in the pancreas to break down fats in the stomach
Enzymes of the digestive system

Digestion: The process of breaking down food into smaller molecules so they can be absorbed by the body. Esophagus: The muscular tube that transfers food from the mouth to the stomach. Peristalsis: The wave-like muscular contractions that push food through the digestive system.
