The ciliated epithelial cells are required to move
particles or mucus in a specific direction. In humans, these cells are mainly present in:
A
Bronchioles and Fallopian tubes
B
Bile duct and Bronchioles
C
Fallopian tubes and Pancreatic duct
D
Eustachian tube and Salivary duct
Show explanation
Explanation: Ciliated epithelial cells help move mucus or particles in a fixed direction. In humans, these ciliated cells line the bronchioles, helping clear inhaled dust, and the Fallopian tubes, helping move the egg towards the uterus. Thus, option 1 (Bronchioles and Fallopian tubes) is correct according to NCERT concepts about ciliated lining in these organs.
🧠Did You Know? In the respiratory tract, cilia beat together to push mucus upward toward the throat, a process called mucociliary clearance.
💡 NCERT Memory Line: Ciliated epithelium is present in the Fallopian tubes and in the bronchi/bronchioles, aiding movement of cells or mucus in a specific direction.
