Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

“When food reaches the stomach, it causes distention, which causes the stretch receptors to be activated". Based on the sentence above, what is the secretion phase for this?

A	Cephalic phase
B	Gastric phase
C	Intestinal phase
D	None of the above

Explanation:

Detailed explanation-1: -Once food has entered the stomach, distension of the stomach initiates a vagovagal reflex (gastric phase) that stimulates further secretion of pancreatic exocrine products.

Detailed explanation-2: -The gastric phase of digestion: During the gastric phase, gastrin is secreted. The stomach stretches and churns while enzymes break down proteins.

Detailed explanation-3: -The gastric phase is a period in which swallowed food and semidigested protein (peptides and amino acids) activate gastric activity. Ingested food stimulates gastric activity in two ways: by stretching the stomach and by gastric contents stimulating receptors in the stomach.

Detailed explanation-4: -The physiologic stimulation of acid secretion has classically been divided into three interrelated phases: cephalic, gastric, and intestinal [2].
