 which part of respiratory system humidify the air

The air is humidified in the respiratory system by the nasal passages and the trachea.

As air is inhaled through the nose, it passes over the mucous membranes in the nasal passages. The mucous membranes are lined with tiny blood vessels, which add moisture to the air as it passes over them. This process helps to humidify the air and makes it easier for the lungs to absorb oxygen.

The trachea, also known as the windpipe, is lined with moist mucous membranes that help to further humidify the air as it travels to the lungs. The trachea also helps to filter out large particles of dust, dirt, and other debris before they reach the lungs.

Together, the nasal passages and the trachea play an important role in humidifying the air and making it easier for the lungs to absorb oxygen. This helps to keep the respiratory system healthy and prevent irritation and damage to the delicate tissues in the lungs.
