Question

Give the functions of ciliated columnar epithelium.

Answer 1

Ciliated epithelium :

1. It may be columnar or cuboidal epithelium in which the cells possess cilia on their free surface.
2. This increases the surface area.
3. It occurs in sperm ducts, uriniferous tubules, the lining of the respiratory tract, and oviducts.

Function

1. The cilia help to push the ovum in the oviduct of the fallopian tube towards the uterus.
2. It helps to push the dust particles and foreign bodies out of the respiratory tract.
3. It secretes mucus which helps to trap the dust particles and thus clears the respiratory tract.
