Question
Which epithelium comprises the mucosa of the stomach?a. Stratified squamous keratinisedb. Stratified columnar ciliatedc. Simple columnard. Stratified squamous non keratinisede. Simple squamous
Solution
The epithelium that comprises the mucosa of the stomach is c. Simple columnar.
Here's a step-by-step explanation:
- The stomach is part of the digestive tract, which is lined by a mucous membrane.
- This mucous membrane is made up of epithelial cells, which are the body's first line of defense against harmful substances.
- The type of epithelial cells found in the stomach is the simple columnar epithelium.
- Simple columnar epithelium is made up of a single layer of tall and narrow cells.
- These cells have the ability to secrete and absorb substances, which is crucial for the stomach's role in digestion. They secrete mucus that protects the stomach lining from the acidic gastric juices.
- Therefore, the correct answer is c. Simple columnar.
