How to Play
this phase of digestion occurs when a stimulus from the intestine sends feedback and instructions to other portions of the GI tract
t/F: the submandibular gland is a mucous secreting gland.
atropine inhibits ____ activation of salivary ducts
T/F: Pancreatic juice is isotonic.
T/F: The ducts of the salivary gland are impermeable to water, while the ducts of the pancreas are permeable to water.
T/F: In addition to GRP, amino acids and peptides can stimulate G cells to release gastrin.
this channel is involved in cycling Cl back into the lumen of the pancreatic duct
type of acinus that produces watery saliva that contains a amylase, lysozyme, peroxidases, and IgA
Which portion of the salivon primarily receives innervation for the autonomous nervous system
the major sympathetic receptor at acinar cells is ____.
produces 25% of saliva
T/F: Only parasympathetic innervation stimulates saliva production
produces 5% of saliva
T/F: Pancreatic acinar cells are responsible for the bicarbonate secretion of the exocrine pancreas
the phase of digestion that begins in the brain. An example includes the origination of the salivary reflex at the site of food
T/F: The composition of saliva changes with the flow rate.
Aldosterone acts on salivary duct cells to increase the reabsorbtion of which two ions?
Although, sympathetic innervation acts to activate salivary acinar cells, what prevents the release of saliva?
gland that is the main contributor to saliva (70%)
major event that occurs during the interdigestive phase
T/F: The ductal portion of the salivon acts to modify the ionic composition of saliva
Dehydration, fear, sleep, aand anticholinergic drugs ____ (promotes... inhibits) activation of salivary glands
These cells in the duodenum respond to H+ ions and release secretin in response to higher acid concetration
T/F: In the intestinal phase, gastrin and the vagus nerve act to stimulate zymogen granule release.
T/F: Patients with cystic fibrosis can present with malabsorption and steatorrhea, due to a deficiency of pancreatic enzymes
In the intestinal phase, this hormone acts at acinar cells to cause the release of zymogen granules
In the gastric and cephalic phases, the pancreatic acinar cells release zymogen granules in response to activation of muscarinic cholinergic receptors as well as receptors for whic
Enzyme responsible for activation of most of the pancreatic proteolytic emzymes
Channel involved in taking the Cl out of the lumen of the pancreatic duct, while taking Bicarbonate from the blood into the lumen of the pancreatic duct
bicarbonate concentration in the exocrine pancreatic juice is ____ than plasma
T/F: Saliva is usually a hypotonic solution.
unit of salivary gland that is responsible for producing saliva
At low flow rates, which two ions dominate pancreatic juice?
Which neurotransmitter stimulates the release of gastrin from G cells in the stomach?
This hormone activates the CFTR channel
Saliva is characterized by the presence of which two molecules (ions)?
T/F: Saliva secretion is controlled by GI hormones.
enzymes within salivary or exocrine glands are released in ...
the parasympathetic nervous system cause vasodilation by using which NT?
Where does protein digestion begin?
solely serous secreting salivary gland
atropine inhibits ___ receptors
this type of acinus helps to lubricate food
In the gastric and cephalic phases, the vagus can act to stimulate the release of bicarbonate by the duct cells. In the intestinal phase, what stimulates the release of bicarbonate
This enzyme is bound to the duodenal epithelial cells and activates trypsin
pavlov's classical conditioning is an example of which phase of digetion?
Would saliva be most plasma in high or low flow rates?
this phase of digestion occurs when a stimulus from the stomach influences function of the small intestine and other portions of the GI tract.
mucous secreting salivary gland
At high flow rates, which two ions dominate pancreatic juice?
released by pancreatic ductal cells to neutralize the acidic chyme from the stomach
These cells in the duodenum are activated mainly by fat (or amino acids) and release CCK to increase pancreatic enzyme release
