Question

The ciliated columnar epithelial cells in humans are known to occur in:

• A. Fallopian tubes and urethra
• B. Eustachian tube and stomach lining
• C. Bronchioles and fallopian tubes
• D. Bile duct and oesophagus

Answer 1

The correct option is C Bronchioles and fallopian tubes

Ciliated epithelium has these hairs, called cilia, which move back and forth to help move particles in the human body. We find ciliated epithelial tissue in our respiratory tract and in the fallopian tubes of women. Ciliated epithelium contains goblet cells, which secrete mucous.
So bronchioles have cilia to move dust particles out of the air passage. Fallopian tubules have cilia to move the ovum from the ovaries to the uterus.
