It plays a vital role in facilitating the process of respiration, which involves taking in oxygen and expelling carbon dioxide. The main organs of the respiratory system include: 1. Nose and Nasal Cavity: The nose filters, warms, and moistens the air we breathe. The nasal cavity contains small hairs called cilia that trap dust and particles, preventing them from entering further into the respiratory system. 2.
