E) alveoli Relaxation of the diaphragm allows air to flow back out the lungs during exhalation. The pleural membrane seals the lungs and maintains the lungs at a pressure slightly below that of the atmosphere when the lungs are at rest. During inspiration, the inspired air enters through the nose or mouth, travels through the pharynx to the larynx, passes through the glottis and into the trachea. The pharynx, also known as the throat, is a muscular funnel that extends from the posterior end of the nasal cavity to the superior end of the esophagus and larynx. e.

This is due to the influence of the hormone testosterone, which stimulates the overall growth of the larynx resulting in a deeper voice with time. Pulmonary ventilation is the process of moving air into and out of the lungs to facilitate gas exchange. a. atelectasis There are two groups of muscles that are associated with the larynx, the extrinsic and intrinsic muscles.
