What is the function of the phraynx in the digestive system?

Answer 1

The Pharynx is a muscular funnel (about 13cm long) that is divided into 3 parts; the nasopharynx, the oropharynx and the laryngopharynx. Air passing through the nasopharynx has to turn 90degrees downwards and any large particles (more than 10 micrometers) can't make the turn and crash into the wall of the nasopharynx and stick to the mucosa near the tonsil (well positioned to respond to airborne pathogens). The oropharynx is the area near the root of the tongue and ends just before the epiglottis (the flap that prevents food going into the lungs when swallowing). The laryngopharynx starts at the tip of the epiglottis and ends where the oesophagus begins (the tube that goes to the stomach). The nasopharynx passes only air, whereas the oropharynx and laryngopharnx pass air, food and drink.

Answer 2

Pharynx is just a fancy (i.e. medical) term for the throat. It is where your uvula is located. Your tonsils. Your epiglottis.

Answer 3

It is the passageway for food and water. It ensures that food or drink goes down the right "pipe"
