Altered alimentary canal (physiology (stomach= mechanical breakdown,…
Altered alimentary canal
Organs = Oral cavity, esophagus, pharynx, liver, pancreas, small intestine, large intestine, stomach gall bladder
Special structures = duodenum, jejunum, ilium, cecum, cardial sphincter, pyloric sphincter, gastric pits
Basic nutrients needed = Carbs, proteins, lipids, vitamins, minerals, water.
physiology
oral cavity = ingest, begin mechanical breakdown by mastication & propulsion
-
-
stomach= mechanical breakdown, propulsion, digestion, absorption.
-
-
-
small intestine = mechanical breakdown, propulsion.
-
duodenum = contains brunner cells & the hepatopancreatic sphincter which allows bile & pancreatic juices to enter
-
large intestin = digestion, absorption, propulsion. defecation.
-
appendix = contains MALT, body immunity, contains good bacteria also.
-
-
enzyme responsible for digesting different nutrients = lipase = lipids. proteases = proteins. amylase = carbs. nucleases = nucleic acids
-
lack of organs involved =no enzymes can be added to food because hepatopancreatic sphincter allows for bile & pancreatic enzymes to enter duodenum
Feeding tube bypass esophagus, stomach & duodenum
lack of stomach & duodenum involvement, hepatopancreatic sphincter can not release bile/pancreatic juices to aide in digestion/absoption
food impacted with tube = needs to be certain mixture so that tube doesnt get clogged while feeding.
provided in tube = proper nutrients, correct formula, store it in a refrigerator after opening and inject in tube at room temp. dietician/doctor can be consulted over which tube formula is best for the patient.
All the correct nutrients need to be provided in the feeding tube because of how the stomach, esophagus, & duodenum are being bypassed. they arent able to play their vital roles during digestion
-
feeding tube needs to remain cleared, wash with warm water before and after each feeding.
