Question
The interior lining of the small intestine is protected from ulcer development by a thick layer of mucus.
- A) True
- B) False
Solution
Answer
A) True
The interior lining of the small intestine is indeed protected from ulcer development by a thick layer of mucus. Mucus is secreted by goblet cells found in the epithelial lining of the intestine, serving several crucial functions. It acts as a barrier between the intestinal lumen and the epithelial cells, preventing damage from acidic gastric contents and digestive enzymes. This protective layer of mucus helps to maintain the integrity of the intestinal lining and plays a critical role in preventing the development of ulcers, which can occur due to excessive acid exposure or injury from various substances. Without this mucus layer, the risks of inflammation, irritation, and ulceration significantly increase, leading to conditions such as gastritis or peptic ulcers. Thus, the statement is true.
