| incisors | the teeth that are sharp and are used to cut food. |

| premolars | crush and grind food, but are a bit smaller than other teeth that do this. |
| molars | crush and grind food |
| bolus | a solft lump of chewed food ready for swallowing |
| soft palate | seals off the nose and keeps food from rising up into it during the act of swallowing |
| epiglottis | a small flap of cartilage that that covers the larynx during swallowing and prevents food from entering the bronchial passage ways |
| gastric juices | a mixture of many chemicals secreted by the stomach that digest food |
| hydrochloric acid | the most powerful acid in the human stomach that activates the difestive chemicals that are in gastric juice. Kills any pathogenic microsopic organisms that might have been ingested, dissolves good so that it is easier to absorb |
| chyme | food that has been churned and turned into a liquid mush and mixed with gastric juices |
| pyloric sphinctor | a ring of muscles that controls the flow of digested food from the stomach into the small intestine |
| intestinal villi | very tiny finger-like projections that line the small intestine and whose job is to absorge nutrients from digested food |
| nutrient absorbing cells | these are the outer most layer of the small intestines |
| cecum | the first part of the large intestine; the muscles here push chyme into the colon. |
| colon | the middle part of the large intestine; the main function here is to absorb water; but nutrients are absorbed here too |
| rectum | last part of the large intestine, and waste products that make it to this point are the feces which must be expelled |
| glygogen | this is a polysacharride that the liver stors extra sugars as. The liver can readily turn it into glucose when the body needs energy |
| pancreas | makes several digestive juices for help in digestion. It also produces sodium bicarbonate a "base". It injects these juices into the small intestine to neutralize the acids in the chyme. |
