Ciliated epithelial cells are present in:
Show Hint
Ciliated epithelium is vital for maintaining clean and functional respiratory pathways.
- Kidneys
- Intestines
- Blood Vessels
- Bronchioles
The Correct Option is D
Approach Solution - 1
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.
Approach Solution -2
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:
- Respiratory tract : Cilia in bronchioles move mucus and trapped particles out of the lungs.
- Reproductive tract : Cilia in the fallopian tubes help move the egg toward the uterus.
Other options:
- Kidneys : Primarily composed of nephrons and do not have ciliated epithelial cells.
- Intestines : Have absorptive cells but not ciliated epithelial cells.
- Blood vessels : Lined with endothelial cells, not ciliated epithelial cells.
Ciliated epithelial cells are most commonly found in bronchioles .
