Ductus parotideus · Vývod příušní žlázy
Digestive system
Looks like
A tube about 5 cm long running across the cheek from the parotid gland to open inside the cheek opposite the upper second molar.
What it does
Carries saliva from the parotid gland into the mouth.
Keeping it well
A stone or narrowing can block it: swelling in front of the ear at meals. Deep cheek cuts can sever it.
