The negative pressure system of the respiratory system involves the establishment of a negative pressure gradient between the alveoli and the external atmosphere. A less prominent inferior thyroid notch is present along the base of the thyroid cartilage. Air inhaled through the oral cavity enters the pharynx at the oropharynx. Your larynx is a hollow tube that connects your throat (pharynx) to the rest of your respiratory system. 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.

Opening and closing of the larynx are determined by the intrinsic and extrinsic muscles acting on the elastic forces in the tongue, pharynx, larynx, and trachea. Surrounding the lungs are sets of muscles that are able to cause air to be inhaled or exhaled from the lungs. The pharynx is opened or closed by two mechanisms: (1) Contractions of the cricothyroid and of the intrinsic muscles of the larynx open and close the vocal cords. pg. 440, The function of the C-rings of hyaline cartilage in the trachea is to keep the airway patent or open for breathing.
