The statement is correct. The inhaled air first passes through the nasal cavity, where it is filtered, warmed, and humidified by the mucous membrane and the blood vessels in the nasal conchae. This process continues as the air travels through the rest of the upper respiratory system, including the pharynx and larynx, and into the lower respiratory system, including the trachea, bronchi, and bronchioles.
