Question

which function is performed by both goblet cells and lacrimal glands?
○ digestion
○ stress regulation
○ protection
○ growth regulation

Explanation:

Goblet cells secrete mucus, which protects epithelial tissues (e.g., in the digestive and respiratory tracts) by trapping particles and preventing damage. Lacrimal glands secrete tears, which protect the eye by lubricating it, washing away foreign particles, and containing antimicrobial substances. Digestion is not a function of lacrimal glands. Stress regulation is done by organs like the adrenal glands, not goblet cells or lacrimal glands. Growth regulation is managed by hormones (e.g., growth hormone) and is not a role of these structures. So the common function is protection.

Answer:

C. protection
