| Esophagus | Food tube that is located posterior to the trachea (wind tube). It is the passage w ay for food to the stomach from the oral cavity. |
| Stomach | Chemically and mechanically breaks down the bolus into creamy paste called chyme. |
| Chief Cells | Located in the stomach. Produces pepsin, which is used to start the break down of proteins. |
| Parietal Cells | Located in the stomach. Produces hydrochloric acid in the stomach that is used to chemically break down of food (increase the efficiency of Pepsin) and kill bad bacteria. |
| Duodenum | First 10 inches of the small intestine. Location of chemical digestion and absorption of nutrients and water. |
| Jejunum & Ileum | Last 20 ft. of the small intestine. Absorption of nutrients and water. |
| Gall Bladder | A 4 in. long green organ located on the interior side of the liver. Delivers bile to the duodenum, which is used to break down fats. |
| Pancreas | Releases digestive juices used to chemically break down food. Produces insulin, which is used to help control blood sugar levels. |
| Large Intestine | (Terminal End) last 5 ft. of the digestive tract. Absorption of most water and vitamine K and breaks down, with the help of bacteria, fiber and other tough materials. |
| Rectum | 4 in. long tube at the end of the digestive tract. Store the the compacted feces before it is expelled out of the anus. |
| Lymphatic Vessels | Absorbs and transports fatty acids from the small intestine to the bloodstream. |
| Capillaries | Absorbs sugars, amino acids (proteins), and water from both intestines and then transports it to the bloodstream. |
| Appendix | A small appendage the attaches to the beginning of the cecum. It helps capture and store bacteria found in the chyme. |
| Liver | Produces bile that is used to break down fats in the digestive system, detoxifies the blood and stores vitamins. |
