| Question | Answer |
|---|---|
| Organ that secretes the most potent digestive enzymes | pancreas |
| Organ that secretes bile | liver |
| the organ that secretes trypsinogen and chymotrypsinogen | Pancreas |
| The organ that secretes hydrochloric acid and pepsinogen | stomach |
| most digestion and absorption takes place in this part of the small intestine | duodenum |
| the common bile duct empties into this structure | duodenum |
| the stomach mashes food into a paste called________ | chyme |
| microvilli are most prevalent in this structure | duodenum |
| the primary autonomic nerve that supplies the GI tract | Vagus |
| A large intestine structure | Colon and Cecum |
| The ______, jejunum, and ilium form the small intestine | Duodenum |
| Food tube; the pharynx to stomach | Esophagus |
| organ that receives blood from hepatic portal circulation | Liver |
| organ "bracketed" by the LES and pyloric sphincter | Stomach |
| Ascending, tranverse, descending, Sigmoid | Colon |
| The appendix attaches to this structure | cecum |
| valve between the small intestine and large intestine | Ileocecal |
| gastric reflux involves this valve | LES |
| Located in the thoracic cavity | Esophagus |
| Hepatic flexure and splenic flexure | colon |
| Sucrase, Lactase, Maltase | Disaccharides |
| mechanically breaks a large fat globule into many smaller fat globules | Bile |
| The enzyme that splits fats into fatty acids and glycerol | Lipase |
| The enzymes secreted by the duodenum; they split sucrose, maltose, and lactose into glucose, fructose, and galactose | Disaccharides |
| trypsinogen and chymostrypsinogen | Protease(s) |
| Responsible for gastric PH | HCl |
| A deficiency causes pernicious anemia | Intrinsic Factor |
| Digestive enzymes that yield amino acids | Protease(s) |
| Hormone secreted by the walls of the duodenum; Stimulates the pancreas to secrete potent digestive enzymes | Cholecystokini |
| Hormones secreted by the walls of the duodenum; stimulates the pancreas to secrete a bucarbonate-rich secretion | secretin |
| Hormone secreted by stomach; causes the secretion of HCl | Gastrin |
| Enzymes that digest carbohydrates/starches to disaccharide stage | Amylase(s) |
| What covers the glottis, thereby preventing the entrance of food and water into the respiratory structures | epiglottis |
| What is a hollow tube that carries food from the pharynx to the stomach | Esophagus |
| What delivers chyme to the duodenum at the proper rate | Stomach |
| With which word is deglutition associated with | swallowing |
| what is paralytic ileus | the slowing or cessation of peristalsis |
| what best describes the omentum and the mesentery | serous membrane |
| what are some functions of the stomach | -secretion of intrinsic factor and HCl, delivers chyme to the duodenum |
| lipases,preteases, and amylases are | digestive enzymes |
| fat digestion is accomplished by... | bile and lipase |
| what contracts in response to cholecystokinin | gallbladder |
| what does this statement best describe: A large fat globule is mechanically broken into smaller fat globules | emulsification |
| what organ is essential to life out of : liver, gallbladder, appendix, stomach | liver |
| what secretes the most potent digestive enzymes | pancreas |
| what is the duodenum most concerned with | digestion and absorption |
| what empties bile into the duodenum | common bile duct |
| Relaxation of the sphincter of Oddi allows | the bile to enter duodenum from the common bile duct |
| Amylase and disaccharides are both: | digest carbohydrates |
| what do the canaliculi, hepatic duct, and cystic duct do | carry bile |
| the digestive end products are absorbed into the ____ | portal circulation |
| trypsin is : | -proteolytic -pancreatic -digestive |
| what is duodenum, jejunum, and ileum most related to | the small intestine |
| what chemical aid unravels dietary protein and decreases bacteria in the stomach | HCl |
| What is ptyalin | salivary amylase |
| what is the most important nerve of the digestive tract | the vagus nerve |
| which drug action increases gut motility and is therefore used in the treatment of paralytic ileus? | activates muscarinic receptors |
