Most inspired particles such as dust fail to reach the lungs because of the
a. action of the epiglottis
b. abundant blood supply to nasal mucosa
c. porous structure of turbinate bones
d. ciliated mucous lining in the nose

The answer is D. Ciliated mucous lining in the nose.

Explanation:

Most inspired particles, such as dust, do not reach the lungs due to the CILIATED MUCOUS LINING OF THE NOSE. The nostril is covered with a mucous membrane that has a mucus-producing epithelium, and has hair cells covered with thin hairs, called vibrating cilia, which displace mucus, immune system cells, and numerous substances capable of blocking bacteria, Viruses and harmful substances. It is the first line of defense of the immune system.
