I know the deal about sneezing (the tear ducts are jolted so they create the "tears") but what about when a person yawns???

saorsie, is that how you build up points here? Answer questions with whatever comes to mind??? Do I live with frogs? Come on now, go convince mommy that you're a good boy and can go back to watching Barney and stop killing off the world with your endless stupidity.

There are two possible explanations:
1- During a yawn, there is a slight increase in pressure inside the skull (likely caused by slight increases in the amount of oxygen taken in during a deep yawn). This causes the cerebrospinal fluid (CSF), the fluid that surrounds the brain and flows through the brain's ventricle system, to be forced out faster than normal. That fluid enters the lachrymal (tear) system. That increase in fluid pushes out the tears.
2 - the more simplistic reason may be that when you yawn you scrunch up a bunch of facial muscles. That causes the tear glands and ducts to be squished, forcing out some tears.
Yawning yet?

The increase of pressure in the nasal cavities pressing on the tear ducts will produce a slight watery eye.

because the eyes,ears, nose, and throat are all connected. that why there are doctors who specialize in that field. also, if you get an eye lash in your eye, or a bad tickle in your throat your nose will run.
