| A | B |
|---|
| teeth | chop and grind |
| saliva | contain water and the amylase; moistens food and begins the chemical digestion of starch |
| tongue | mixes the food with the saliva and forms it into a bolus |
| esophagus | food is moved from mouth to stomach via this tube by a process called peristalsis |
| stomach | secretion of HCl and pesinogen(->pepsin); churns and mixed food; chemical digestion of protein |
| duodenum | first part of the small intestine; responsible for chemical digestion of protein, lipid and carbohydrate |
| small intestine | =duodenum, (jejunum) and ileum; responsible for chemical digestion and absorption |
| large intestine | = colon + rectum |
| rectum | stores solid waste prior to egestion |
| salivary glands | production and secretion of saliva |
| gall bladder | stores bile and releases it into the duodenum |
| liver | makes and secretes bile |
| pancreas | produces digestive enzymes(amylases, proteases and lipases) and bicarbonate ions and releases these into the duodenum |
| enzyme | chemical that breaks down large food molecules into smaller molecules |
| bile | yellow-green fluid that emulsifies fat and oil, increaseing the surface area that lipases can then act on |
| colon | additional absorption of water causing waste to become more solid. Houses bacteria that synthesize vitamins, which are absorbed across the intestinal wall |
