| Question | Answer |
|---|---|
| Digestion begins | at the mouth w/ ingestion, chewing & salivation |
| Which enzyme begins the breakdown of food | amylase |
| Pharynx does what to the trachea | closes & seals during swallowing to keep food out of it |
| 3 sections of the pharynx | oropharynx, nasopharynx, laryngeal pharynx |
| Esophagus has 2 sphincters | Upper/hypopharyngeal (prevents air from entering the esophagus during inspiration) & lower/gastroesophageal/cardiac (prevents reflux of food/gastric contents back into the esophagus) |
| 4 sections of the stomach | cardia (proximal end), fundus, body (middle section), antrum |
| What controls the rate @ which food moves through the stomach | gastroesophageal & pyloric sphincters |
| How much gastric juices are produced daily | 1500-3000ml these juices aid in digestion & mixing food w/ chyme |
| Mucosal cells secrete mucus to act as | a lubricant & to protect the stomach lining, synthesize prostaglandins, unsaturated fatty acids,the role of gastrin |
| Stomach's role via hormone is in | hunger & satiety |
| The stomach produces which hormones | Ghrelin which travels to the brain & turns on/off the hunger cells/satiety cells & stimulates gastric emptying |
| The arterial blood supply is through which plexus & venous drainage through | celiac plexus, splenic & gastric vein |
| The small intestine has 3 sections | duodenem, jejunum, ileum |
| Small intestine functions in | digestion, nutrient absorption |
| Small intestine 4 layers are | mucosa: facilitates nutrient absorption, epithelial: covered w/ villi which increase surface area for absorption, muscularis: helps move intestinal contents forward, serosa: helps maintain position of the intestine w/i the abd cavity |
| Instestinal hormones & enzymes are | hormones affect gastric enzymes to stimulate & inhibit gastric motility (motilin, secretin, cholecystokinin), digestive enzymes facilitate absorption of nutrients through small intestine(amylase, trypsin, lipase) |
| Muscle contractions 2 types are | peristalsis & haustral segmentation |
| this muscle contractions | mix the chyme & digestive juices, facilitate nutrient absorption, & moves the mixture forward |
| Intestinal reflex inhibits | motility of small intestine |
| The large intestine receives arterial blood via the | superior & inferior mesenteric artery |
| Intesting 5 primary defense mechanisms are | mucosal barrier, gut motility, gut immunity, gastric acid, gut flora |
| The peritoneum lines the | abdominal cavity & covers most of the intraabdominal organs |
| The 2 functions of the peritoneum are | support abdominal organs & serves as a conduit for blood vessels, lymph vessels, & nerves of abdominal organs |
| The peritoneum as behaves as a | semipermeable membrane |
| The liver is the largest or smallest organ in the body & is located where | largest & RUQ under the diaphragm |
| Kupffer cells filter what | bacteria & foreign substances |
| Glisson capsules is a | connective tissue capsule covering the liver |
| The liver's main 4 functions | meabolize & store nutrients, synthesize clotting factors & breakdown RBCs, detoxify the blood, & produce bile |
| Abdominal xray is good for diagnosing | bowel obstruction, bowel perforation, also id's Ng/feeding tube location |
| Ultrasound is good for | visualization of organs, detecting bile or blood flow obstructions, id ascites |
| CT scan provides | cross section view evaluates massess, abnormalities found, only catches tumors over 2 cm |
| MRI scan |
