 * The air enters the body through the mouth or nose and goes into the pharynx. From there it goes into the larynx then to the trachea. The air then comes into the bronchus and then the bronchioles absorb the oxygen to be cycled through the body. After going throughout the body, the oxygen comes back to the lungs and goes back out as carbon dioxide.
 * The respiratory system helps oxygen and carbon dioxide enter and exit the body. This process allows for cellular respiration, a process essential to maintaining homeostasis.
 * The pharynx connects the oral cavity to the esophagus and the stomach, which the the larynx does not.
 * sinusitis is when the nasal sinuses become inflamed
