At this point, the elastic nature of the lungs causes them to recoil back to their resting volume, restoring the negative pressure gradient present during inhalation. In addition, it protects the respiratory tract by warming and moistening the air and propelling foreign particles upwards towards the pharynx for expulsion. A) vital capacity Between the ribs are many small intercostal muscles that assist the diaphragm with expanding and compressing the lungs. What protects the superior opening of the larynx? The main function of the trachea is to transport air in and out of the lungs during the act of breathing. 500 mL The one advantage of breathing through the mouth is that its shorter distance and larger diameter allows more air to quickly enter the body. The mucosa lined cavity of the larynx extends from its superior opening (laryngeal inlet) to the inferior border of the cricoid cartilage which is continuous with the lumen of the trachea.
