The chief cells secrete pepsinogen in response to gastrin and especially Ach, and ACh also stimulates mucus secretion.
12.
The gastric chief cells of the stomach secrete enzymes for protein breakdown ( inactive pepsinogen, and in infancy rennin ).
13.
Achlorhydria may also be documented by measurements of extremely low levels of pepsinogen A ( PgA ) ( ) in blood serum.
14.
The hormone gastrin and the vagus nerve trigger the release of both pepsinogen and HCl from the stomach lining when food is ingested.
15.
The precursor of pepsin, pepsinogen, is secreted by the stomach, and is activated only in the acidic environment found in stomach.
16.
With an impulse from the vagus nerve, pepsinogen is secreted into the stomach, where it mixes with hydrochloric acid to form pepsin.
17.
The glandular portion produces hydrochloric acid and enzymes such as pepsinogen, as well as bicarbonate and mucus that helps prevent self-digestion.
18.
Hydrochloric acid activates pepsinogen into the enzyme pepsin, which then helps digestion by breaking the bonds linking amino acids, a process known as proteolysis.
19.
Histamine and gastrin act synergistically as the most important stimulators of hydrochloric acid secretion from parietal cells and stimulators of secretion of pepsinogen from chief cells.
20.
In addition, in the bat " Plecotus auritus ", fish and some amphibians, glands secreting pepsinogen or hydrochloric acid have been found.
