The Correct Option is B
Solution and Explanation
The question asks us to identify the type of cells whose secretions protect the lining of the gastro-intestinal tract from various enzymes.
The options provided are:
- Chief Cells
- Goblet Cells
- Oxyntic Cells
- Duodenal Cells
To determine the correct option, let's analyze each one:
- Chief Cells: These cells are located in the stomach and are responsible for secreting pepsinogen, a precursor to the enzyme pepsin. They do not protect the lining of the gastro-intestinal tract.
- Goblet Cells: These are specialized epithelial cells whose primary function is to secrete mucus. This mucus coats the lining of the gastro-intestinal tract, forming a protective barrier against digestive enzymes, acidic conditions, and physical damage.
- Oxyntic Cells: Also known as parietal cells, these are found in the stomach and secrete hydrochloric acid, which aids in digestion but does not protect the lining.
- Duodenal Cells: These cells are part of the lining of the duodenum and have various functions, but they do not specifically protect the gastro-intestinal tract with secretions.
Conclusion: Goblet Cells are the cells whose secretion, mucus, protects the lining of the gastro-intestinal tract from various enzymes and acid. Thus, the correct answer is Goblet Cells.
