Full Answer
Gastrin is a digestive hormone that is responsible for the stimulation of acid secretions in the stomach. These secretions are stimulated by the presence of ________. Which of the following is not a factor that helps create the stomach mucosal barrier?
The main chemical activity of the stomach is to begin the digestion of proteins. Chemical digestion of lipids is initiated in the mouth. The function of the enzyme salivary amylase is to begin digesting proteins.
The acid secretions from the stomach would be sufficient to digest this food. This type of food would cause secretion of gastrin to cease, causing digestive upset. Severe indigestion would occur, caused by the lack of sufficient digestive enzymes.
Gastric secretion is enhanced by very low pH (below a pH of 2). Gastric secretion can be stimulated before food has entered the mouth. Select the correct statement about digestive processes. Chyme entering the duodenum can decrease gastric motility via the enterogastric reflex.
Bile functions to carry bilirubin formed from breakdown of worn-out RBCs. Bile contains enzymes for digestion. Gastrin, histamine, endorphins, serotonin, cholecystokinin, and somatostatin are hormones or paracrines that are released directly into the lamina propria.
Gastric secretion can be stimulated before food has entered the mouth. The presence of food in the stomach prevents hormonal control of gastric secretion. Vagus stimulation of the stomach results in decreased secretion of gastric juice. Gastric secretion is enhanced by very low pH (below a pH of 2).
