During the process of pulmonary ventilation, atmospheric air must travel through the airways. This path starts in the nasal passages where the air enters and is partially filtered and humidified. Subsequently, the air passes through the pharynx, part that is shared with the digestive system and where the epiglottis is, only then passes through the larynx. The air then reaches the trachea, a cartilaginous tube that also has mucus as a barrier for filtration. From the trachea, air is carried to the bronchi, bronchioles and then finally to the alveoli, which are small bags covered by capillaries that receive air so that hematosis can then occur.
