Digestive System The digestive system is a group of organs that break down, or digest, food so your body can get nutrients. The main organs of the digestive system make one long tube through the body. This tube is called the digestive tract. The digestive tract includes the mouth, pharynx, esophagus, stomach, small intestine, and large intestine.

Types of Digestions Mechanical Digestion: Grinding, Cutting and Churning. Example: Mouth: This is when your teeth grinds the food. Stomach: This is when your stomach churns the food.

Types of Digestion Chemical Digestion: Anything that has something to do with saliva, enzymes, and chemicals. Example: Mouth: This is when saliva breaks down the food. Stomach: This is the moment when gastric juices break down the food, food is now called chyme. Chyme in the stomach
