AIIMS 2019 Zoology Epithelial Tissue MCQ Question

Goblet cells are specialized epithelial cells responsible for the secretion of mucus, which plays a crucial role in protecting and lubricating the surfaces of mucus-secreting organs such as the intestines and respiratory tract. In contrast, Paneth cells are involved in the secretion of antimicrobial substances in the intestines, oxyntic cells (also known as parietal cells) secrete hydrochloric acid (HCl) in the stomach, and peptic cells (chief cells) produce digestive enzymes like pepsinogen. Thus, while all these cell types have important functions, only goblet cells are specifically associated with mucus secretion.
