body system
| Question | Answer |
|---|---|
| creatine | used to break down red blood cells |
| metabolic function | breaking down into viable usable components |
| sigmoid colon | s shaped stores stool |
| lower esophageol sphincter | rings of muscles opens to allow bolus closes so stomach can churn |
| stomach | has pepsin & hydrocloric acid churns enzymes & bolus and breaks down |
| pyloric sphincter | way from stomach to small intestines |
| body of stomach | made of rugae that breaks down bolus |
| amino acids | simplest forms of protein |
| rectum | stool released |
| anus | final sphincter muscle |
| glycogen | simplest form of sugar |
| bowel movement | feces defecation |
| papillae | taste buds pain & nerve receptors |
| gastro intestinal tract | GI |
| jejunam | absorption starts |
| osmosis diffusion | absorb through cell wall |
| duodenum | the opening |
| gall bladder | small pear shaped storage unit behind liver stores bile & salts |
| villi | small hairlike structures |
| peristalsis | involuntary wavelike motion |
| esophagus | tubelike structure goes through thoracic cavity |
| bolus | already chewed food mixed with saliva |
| deglutition | swallowing |
| sublingual | salivary gland under tongue |
| submandible | salivary gland below jaw |
| parotid | salivary gland below cheek/by eyes |
| throat | 1st passageway for digestion |
| teeth | upper and lower rows performs mastication biting chewing tearing grinding |
| cheek | walls of oral cavity keeps food inside |
| lips | opens & closes controls intake of food & liquid |
| oral cavity | lips, cheek,teeth tongue,throat salivary glands |
| pancreas | large elongated organ behind stomach produces insulin isles of langerhans |
| ileum | end of small intestines |
| tongue | thick flexible muscle covered in papillae aids in speech chewing and swallowing |
| liver | carries out metabolic function fat proteins and carbs dextoxifies by breaking down |
| liver | makes and secretes bile removes nutrients and blood stoes glycogen lipids vit b iron |
| large intestines | cecum,colon,rectum absorbtion of salt and water production of vit k |
| colon | ascending transverse descending ecoli lives here |
| small intestines | electolytes are absorbed here approx 20 ft absorbs chyme |
| small intestines | duodenum, jejunum, ileum uses villi by osmosis and diffusion |
| digestive system | ingestion, eliminates waste absorption of nutrients chemically and mechanically |
| epiglottis | made of flexible muscle aids in swallowing attached to back of tongue |
