Digestive System Digestion is the breaking down of food into nutrients the body can use. The Digestive System is like a long tube. As the food passes through the tube different organs change the food so that the body may use the nutrients stored by the food. I. Parts A. Mouth a. Teeth b. Saliva glands c. Tongue B. Esophagus C. Stomach D. Small intestine a. Liver b. Pancreas c. Gall bladder E. Large intestine II. Job of each A. Teeth- grind up the food B. Saliva gland- produces saliva which helps to change starch into sugar. C. Tongue- helps to move food around in the mouth to mix with the saliva D. Esophagus- food travels down this from the mouth to the stomach E. Stomach- muscles in the stomach move food around where it is broken down further when it mixes with juices the body produces. The food is broken down almost entirely into a liquid. F. Small intestine- lined with blood vessels. Little villi absorb the nutrients and pass them on to the blood. The blood then carry the nutrients to all parts of the body. G. Liver- produces bile which goes into the small intestine which helps to break down fats. H. Pancreas- produces chemicals to help break down fats and starches. Produces insulin which helps break down sugars. I. Gall Bladder- stores the bile which was produced in the liver. It becomes stronger and helps break down fats in the body. J. Large Intestine- Waste and excess water enter your large intestine. The water is removed and the solid waste travels through the large intestine, out of the body.
