Question

Secretion of which hormone is stimulated by strong acid in stomach and intestine?

Answer 1

Digestion is accomplished through a variety of mechanical and chemical processes. The buccal cavity is responsible for the mechanical digestion processes. The following are the mouth and buccal cavity's two primary functions:
Mastication of food - This is done with the help of the teeth, tongue, and saliva.
Food lubrication - Saliva helps to transform masticated food into the bolus by lubricating the food ingredients.

Complete answer:
Secretin is released into the bloodstream when hydrochloric acid moves from the stomach to the duodenum. By regulating secretions in the stomach, pancreas, and liver, it manages water homeostasis throughout the body and influences the environment of the duodenum. As a result, the hormone release is triggered by the lumen's acidic environment.
Secretin is a digestive hormone that regulates gastric acid secretion and pH levels in the duodenum. It's made from the upper half of the small intestine's wall (the duodenum).
Secretin also suppresses gastrin production, which slows gastric emptying by triggering the initial flow of hydrochloric acid into the stomach.
Secretin is used in pancreatic function diagnostic tests; secretin is injected, and the pancreatic output can then be imaged with magnetic resonance imaging, a noninvasive procedure, or secretions can be collected either through an endoscope or tubes inserted through the mouth and down into the duodenum.

Note:
The enzymes and hormones listed below help to carry out chemical processes.
Amylases and Lysozymes in Saliva
The mouth cavity is the source of these enzymes. The primary purpose of these enzymes is to hydrolyze carbohydrates and break them into smaller pieces. These enzymes have the following functions:
Salivary amylases — at an acidic pH, salivary amylases convert starch molecules to maltose.
Lysozymes is a type of enzyme that fights bacterial infections. Antibacterial agents are another name for them.
