Why do humans cry?

Andy Leonard  asked the Naked Scientists:
   
Chris,

This question was inspired about a topic that your show covered a while back on laughter, and why humans laugh etc.

My question is about the opposite: Why do humans cry, what purpose do tears have, and why do we cry at times of great distress and also joy?

Andy Leonard

What do you think?

Hey Andy!!
Humans cry because of the following reason!!
There are tear glands in our eyes!!
When a moment of joy or sadness comes then these tear glands gets excited and excrete tears!!
Since our eyes can't retain tears so they flow from our eyes!!
You have seen that tears flow from our eyes when we cut onion!!
This is because of this reason onlY!!
Good Luck
