Ciliated epithelium is vital for maintaining clean and functional respiratory pathways.
Ciliated epithelium location:
(A) Kidneys - Incorrect: Renal tubules have microvilli but lack motile cilia.
(B) Intestines - Incorrect: Intestinal epithelium contains absorptive cells with microvilli, not cilia.
(C) Blood Vessels - Incorrect: Vascular endothelium is non-ciliated squamous epithelium.
(D) Bronchioles - Correct: The respiratory tract (especially bronchioles) contains pseudostratified ciliated columnar epithelium that moves mucus.
The correct answer is (D) Bronchioles, where cilia function in the mucociliary escalator mechanism.
Ciliated epithelial cells are specialized cells with hair-like structures called cilia that help in movement or transport of substances. They are commonly found in:
Other options:
Ciliated epithelial cells are most commonly found in bronchioles .
