LEARNING OBJECTIVES Define the function of the human digestive system. Identify, label, and describe the functions of the mouth, tongue, teeth, esophagus, stomach, small intestine, and large intestine. Describe what happens to a piece of food as it goes through the digestive system.
What is a DIGESTIVE SYSTEM? The digestive system breaks down the food we eat into tiny parts to give us fuel and the nutrients we need to live. As food breaks down, we get amino acids from protein, simple sugars from starches, and fatty acids and glycerol from fats.

THE MOUTH Digestion begins in the mouth, where the teeth chew the food. Glands in the mouth produce a digestive juice called saliva. The tongue mixes the food particles with saliva. The saliva moistens and softens the food so that it can be swallowed easily. When a person swallows food, it passes through the pharynx, or throat, into the esophagus. 1 2
1 THE ESOPHAGUS 2 The esophagus is a tube through which food passes from the pharynx to the stomach. In a process called peristalsis, the walls of the esophagus move in waves to push the food down the tube to the stomach. Peristalsis also takes place in the stomach and intestines. 4 3
4 THE STOMACH 3 Everything is blended with digestive juices. Hydrochloric acid kills bacteria. Enzymes break down proteins. 5 6 7 8
THE LIVER 4 3 A green liquid called bile, which is stored in your liver, is secreted to break down fats. 5 6 7 8
4 3 PANCREAS 5 Many kinds of digestive enzymes are made here. 6 7 8
SMALL INTESTINE 4 3 5 Food is mixed with bile from your liver and juices from your pancreas to be sent back to your liver for more processing. 6 7 8
