The pharynx is a hollow tube in the neck that acts as a passage for air to reach the lungs and food to reach the stomach. It is made up of three parts- the upper part, the nasopharynx, the middle part, the oropharynx, and the lowermost part that opens up to both the food pipe and the windpipe, the hypopharynx. The larynx is the part of the throat between the base of the tongue and the windpipe, often referred to as the voice box. Cancer can originate in either the larynx or pharynx, two primary parts of the throat.
