Options
- Abronchioles and fallopian tubes
- Bbile duct and oesophagus
- Cfallopian tubes and urethra
- Deustachian tube and stomach lining
Correct answer
A. bronchioles and fallopian tubes
Step-by-step solution
The columnar epithelium is composed of a single layer of tall and slender cells. If the columnar cells bear cilia on their free surface they are called ciliated columnar epithelium. They are mainly present in the inner surface of hollow organs like bronchioles and fallopian tubes. Their function is to move particles or mucus in a specific direction over the epithelium.
