Gastric Secretion Flashcards
In the gastric phase HCL secretion can be released by stretch reflex what is responsible for this
Myenteric plexus between the circle and longitudinal layer
Vagus nerve
What cells are secretin released from
S sells
Where is secretin realised from
Upper small intestine
What does secretin do
Increases secretion of bicarbonate rich fluid from the pancreas and hepatic duct cells which decreases gastric acid secretion
What does secretin do
Increases secretion of bicarbonate rich fluid from the pancreas (duct cells) and hepatic duct cells which decreases gastric acid secretion but it is released from s cells in the duodenum
other than HCL what does parietal cells secrete
intrinsic factor
what cells make somatostatin
gamma cells g cells
what cells make glucagon
alpha cells
what cells make insulin
beta cells
what hormones do the islets of Langerhans secrete
insulin, glucagon and somatostatin
what is the opening of the pancreas to the duodenum called and what is the sphincter muscle around it
ampulla of vater and sphincter of oddi
what cells secrete bicarbonate and what cells secrete pancreatic enzymes
acinr cells secrete enzyme duct cells secrete bicarbonate
where is cck released
in the duodenum in response to fatty acids or amino acids in the duodenum
what does cck do
act on acinar cells to secrete more digestive enzymes to digest fats and proteins
