Solution:
Parietal cells (or oxyntic cells) secrete hydrochloric acid (HCI) and Castle's intrinsic factor. Chief cells (or peptic cells) secrete gastric digestive enzymes as proenzymes
—
pepsinogen and prorennin. HCI helps in converting pepsinogen to pepsin. Goblet cells secrete mucus which helps to neutralise acid in stomach and protects stomach wall against HCI action.
