Pancreatic Secretion Flashcards
Pancreatic enzymes are synthesized on the (rough/smooth) endoplasmic reticulum of the acinar cells.
Rough ER
________ which is secreted by the S cells of the duodenum, is the major stimulus for bicarbonate-rich secretions from pancreatic ductal cells.
Secretin
Sympathetic stimulation (inhibits/stimulates) pancreatic secretion.
Inhibits
In pancreatic secretions, there is a (reciprocal/parallel) relationship between chloride and bicarbonate concentrations.
Reciprocal
The stimulus for pancreatic (enzyme/aqueous) secretions is digestion products in the duodenum.
Enzyme
The initial pancreatic aqueous secretion is (iso/hypo/hyper) tonic compared to plasma
Isotonic
The two types of cells that comprise the exocrine portion of the pancreas
Ductal cells
Acinar cells
CCK binds to _____ to induce the release of enzymatic pancreas secretions
Vagus nerve
The ductal and centroacinar cells of the exocrine pancreas secrete the aqueous -containing portion of the pancreatic secretion.
Bicarbonate
Pancreatic amylases and lipases are secreted as (active/inactive) enzymes.
Active
Peptide YY secreted by the ileum (inhibits/stimulates) pancreatic secretions.
Inhibits
When the pancreatic flow rate increases, the concentration of bicarbonate in the secretion (increases/decreases) .
Increases
The enzymatic portion of the pancreatic secretion is secreted by (acinar/ductal) cells.
Acinar cells
Pancreatic proteases are secreted in their (inactive/active) forms.
Inactive
The majority of the pancreas is (endocrine/exocrine) in function.
Exocrine
