Major secretion of leader cells
pepsinogen
Major secretion of parietal cells
HCl and intrinsic component
Intestinal epithelium secretes
brush border enzymes (peptidases, lipases,
sucrase, lactase), secretin, and cholecystokinin
pancreas secretes
bicarbonate-rich fluid containing amylase, trypsin,
chymotrypsin, and lipase into the duodenum whilst inspired by secretin
,Gallbladder secretes
Bile in reaction to stimulation of cholecystokinin (CCK)
Sympathetic worried system pastime is normally
inhibitory to GI motility and secretion.
Parasympathetic nervous machine pastime normally
enhances GI motility
Which information is correct approximately the myenteric plexus?
•Another call for myenteric plexus is the Meissner plexus
•The myenteric plexus controls GI motion
•The location of the myenteric plexus is the submucosa
•The myenteric plexus controls GI secretion
The myenteric plexus controls GI motion
What is the function of gastrin?
•Decreases gastric motility
•Stimulates release of histamine
•Increases boom hormone secretions
•Releases large amounts of alkaline juice
Stimulates release of histamine
Which records is correct concerning gastrointestinal motility?
•The SNS increases GI movement
•Propulsive actions are called haustral churning
•Segmented contractions chop and mix the chyme
•None of the above
Segmented contractions chop and blend the chyme
True or False: Babies more youthful than three-4 months are fed only liquids due to the fact their
enzyme structures are too immature
False, Immature GI tract
, osmotic diarrhea
Mechanism: Excess particles in intestinal lumen
motive water access through osmosis
Clinical Examples:
•Lactose intolerance
•Unabsorbed food
•Enzyme deficiencies
•Osmotic laxatives
secretory diarrhea
Mechanism:
Excessive intestinal secretion and
inhibition of reabsorption of fluid and
electrolytes
Clinical Examples:
•Enterotoxins and different bacterial toxins
Exudative Diarrhea
Mechanism:
Proteinaceous exudate, mucus, and
blood in lumen from infected intestinal
wall draws in water by means of osmosis; inflamed
tissue has impaired absorption
Clinical Examples:
-Inflammatory bowel sickness
-Neoplasms
increased motility diarrhea
Mechanism:
Increased intestinal motility decreases
absorption through reducing intestinal
transit time
Clinical Examples:
•Resection or pass of intestine
•Irritable bowel syndrome
