Answer 1

your answer is
answer 1:- The intermediate gastric glands produce most of the digestive substances secreted by the stomach. These glands are narrow tubules composed of three major cell types: zymogenic, parietal, and mucous neck cells. At the base of the glandare the zymogenic (chief) cells, which are thought to produce the enzymes pepsin and rennin. (Pepsin digests proteins, and rennin curdles milk.) Parietal, or oxyntic, cells occur throughout the length of the gland and are responsible for the production of hydrochloric acid, which is necessary to activate the other enzymes. The purpose of mucous neck cells is to secrete mucus.

1. Salivary glands: These produce saliva
2. Gastric glands: These secrete gastric juice 3. Intestinal glands: These secrete intestinal juice
