Like when we try to spit, a small puddle of saliva instantly comes into out mouths before it is spit out.
In: Biology
Saliva is a very important thing for your oral health, speech, and eating. As such, your body is CONSTANTLY producing it to make sure your mouth stays moist for proper function.
There are 3 sets of salivary glands: two each of the Parotid (in the back of your throat, produces about half of the saliva), submandibular (below your mouth, between the jawbones), and sublingual (under your tongue; you can actually see the ducts for these if you pull your tongue back).
By putting pressure on these glands, you can squeeze the saliva out of them and into your mouth.
