The Digestive System

1. Mouth - It chews the food and makes it easier to travel down the esophagus. The saliva produced in the salivary glands in the mouth makes it easier to swallow food. The mouth also contains an enzyme called amylase that digests starch which is found in glucose.
Esophagus -
The food swallowed travels down the esophagus. The esophagus is a tube that connects the mouth to the stomach.
2. Stomach -the stomach temporarily stores the food. Then a chemical reaction occurs. The enzymes start to digest the food. There are acids that dissolve food down into smaller pieces so it can be absorbed into our blood. Then the food is liquefied and travels into the small intestine.
3. Small Intestine - The small intestine is responsible for absorbing most of the nutrients found within the food. The blood leaves the small intestine, carrying away nutrients, water electrolytes, vitamins, minerals, fats and medications to the entire body.
4. Large Intestine - The foods that can’t be digested travel to the large intestine. It moves the waste from the small intestine to the rectum.
