The nasal cavity
Mucus in the nose and trachea traps foreign particles and bacteria. The cilia, tiny hair-like structures in the respiratory tract, move the mucus and trapped particles upwards to be swallowed or expelled. This process helps to protect the lungs and respiratory system from harmful invaders.
it consists of two parts
Yes
lungs
The upper respiratory system employs several mechanisms to filter out dust and bacteria before they reach the lower respiratory system. Cilia, tiny hair-like structures lining the nasal passages and trachea, sweep mucus and trapped particles upward toward the throat, where they can be swallowed or expelled. Additionally, mucus traps dust, pathogens, and other debris, preventing them from entering the lungs. The rich blood supply in the upper respiratory system also helps warm and humidify the air, further protecting the delicate tissues of the lower respiratory system.
