Goblet cells are predominantly found in which organ system?

• A. Thyroid gland
• B. Skin
• C. Digestive tract
• D. Trachea

Answer: (C)

Goblet cells are mucus-secreting cells in the lining of mucous membranes. Their main job is to produce mucins that hydrate into a viscous mucus, which protects and lubricates the underlying epithelium. This function is especially important along the digestive tract, where mucus coats the lining from the esophagus through the intestines to protect it from acids, enzymes, and mechanical wear, and to aid passage of contents. They also appear in the respiratory tract such as the trachea, but the digestive tract has a more extensive distribution of goblet cells overall, making the digestive tract the best match.
