| 9342004162 | stomach | An organ of the digestive system where most mechanical breaking down of food happens |  | 0 |
| 9342004163 | esophagus | A muscular tube that connects the mouth to the stomach. |  | 1 |
| 9342004164 | large intestine | Absorbs water and forms feces |  | 2 |
| 9342004165 | accessory organs | food does not physically enter these organs but they help in the digestion of food. Pancreas, gall bladder, liver |  | 3 |
| 9342004166 | Liver | makes bile, breaks down and eliminates toxins, such as nitrogen containing compounds |  | 4 |
| 9342004167 | mouth | where mechanical and chemical digestion begins |  | 5 |
| 9342004168 | small intestine | Long hollow tube where most chemical digestion and absorption of nutrients occurs |  | 6 |
| 9342004169 | pancreas | produce hydrolytic (digestive) enzymes and release them into the duodenum |  | 7 |
| 9342004170 | gall bladder | An organ that stores bile and releases it as needed into the small intestine |  | 8 |
| 9342004175 | liver | produces bile | 9 | |
| 9342004176 | rectum | stores solid waste and compresses into more solid form | 10 | |
| 9342004177 | chemical digestion | breaking down food with enzymes | 11 | |
| 9342004178 | mechanical digestion | crushing, mashing or breaking down food into smaller pieces to increase surface area making it easier for chemical digestion | 12 | |
| 9342004180 | duodenum | first part of small intestine where chemical digestion of protein, lipid and carbohydrates takes place | 13 | |
| 9342004182 | amylase | enzyme that breaks down starches into sugars found in saliva and small intestine | 14 | |
| 9342004183 | hydrochloric acid | kills bacteria in stomach and gives an acidic environment for enzymes to work | 15 | |
| 9342004185 | villi | fingerlike projections in the small intestine that increase surface area for increased absorption of the products of extracellular digestion | 16 | |
| 9342004187 | pharynx | throat leading to both the respiratory and digestive systems | 17 | |
| 9342004188 | peristalsis | involuntary contractions of smooth muscles in the digestive system; causes food to move through | 18 | |
| 9342004189 | epiglottis | flap of tissue that covers the trachea when swallowing food | 19 | |
| 9342004191 | salivary gland | production of saliva that contains amylase to start chemical digestion of starch in the mouth | 20 | |
| 9342004192 | pepsin | an enzyme that hydrolyzes protein into amino acids in the stomach and small intestine | 21 | |
| 9342004193 | lipase | an enzyme that converts fats (lipids) into fatty acids and glycerol in the small intestine | 22 | |
| 9342004196 | ingestion | process of consuming food and liquid | 23 | |
| 9342004197 | egestion | process of eliminating solid waste | 24 | |
| 9346715223 | Digestion | the breakdown of food into monomers so they can be absorbed into the blood stream | 25 | |
| 9346720223 | ilium | the last section of the small intestine that finishes the absorption of nutrients | 26 | |
| 9346726278 | jejunum | the middle section of the small intestine where absorption of nutrients occurs | 27 | |
| 9346746278 | secretin | hormone released by the small intestine when the pH decreases causing the pancreas to release bicarbonate to neutralize the acid | 28 | |
| 9346774427 | CCK (cholecystokinin) | hormone release from the small intestine to trigger the gall bladder to release bile and the pancreas to release enzymes when food high in lipids inter the small intestine | 29 | |
| 9346815360 | gastrin | hormone released by the stomach to trigger the stomach to release HCL causing the decrease in pH in the stomach | 30 |
