Question

Pharynx is a part of the alimentery canal which extends from nasal cavity and mouth to the larynx and the oesophagus whereas larynx is the upper portion of the trachea.

Answer 1

The nasal pharynx connects to thesecond region, the oral pharynx, by means of a passage called an isthmus. The oral pharynx begins at the back of the mouth cavity and continues down the throat to the epiglottis, a flap of tissue that covers the air passage to the lungs and that channels food to the esophagus.

Answer 2

Answer:

It also connects the nasal system of air chambers and the upper end of the trachea. The opening of the mouth into the pharynx is the oropharynx, and the nasal opening is the nasopharynx. The eustachian tube from the middle ear (see Chapter 10, p. 167) opens into the pharynx on each side.
