Digestive system

  1. 1. Digestive SystemDoesn’t just break down food so you can eat!
  2. 2. Digestive System The digestive system is made up of the digestive tract—a series of hollow organs joined in a long, twisting tube from the mouth to the anus—and other organs that help the body break down and absorb food
  3. 3.  Organs that make up the digestive tract are the mouth, esophagus, stomach, small intestine, large intestine—also called the colon—rectum, and anus. Inside these hollow organs is a lining called the mucosa. In the mouth, stomach, and small intestine, the mucosa contains tiny glands that produce juices to begin the process of digestion. The digestive tract also contains a layer of smooth muscle that helps break down food and move it along the tract.
  4. 4.  Two ―solid‖ digestive organs, the liver and the pancreas, produce digestive juices that reach the intestine through small tubes called ducts. The gallbladder stores the liver’s digestive juices until they are needed in the intestine.
  5. 5.  The small intestine allows the broken down food (in the form of glucose and other molecules of life) to be absorbed by the bloodstream and transported to all parts of the body. The large intestine allows water to be reabsorbed by the body. All leftover wastes are left over to be excreted out of the body. Parts of the nervous and circulatory systems also play major roles in the digestive system.
  6. 6. Digestive System Liver – Controls blood sugar level with the following feedback loop:  If too low, converts stored glycogen (glucose) into sugar  If too high, removes sugar from the blood and stores as glycogen
  7. 7. Diseases/afflictions of the digestive system Diabetes Ulcers Acid reflux/heartburn Stomach or liver cancer Cavities/gum disease/root canal Tonsillitis Gall stones/gall bladder removal
