Answer:
a thick, mucous secretion and active mitosis of epithelial cells
Explanation:
The mucous neck cells of gastric glands serve to secrete mucus. Mucus is a thick sticky secretion that is rich in protein and carbohydrates. Apart from lubricating the stomach lining, its layer serves to protect the cells of the stomach lining from HCl.
To maintain the integrity of the stomach lining, the wore out cells are replaced by the new cells. To serve the purpose, the epithelial cells of stomach lining undergo mitosis and produce new cells to replace the damaged cells.
