Emtional crying is a way of releasing certain chemicals, hormones and proteins that are made and built up when we experience strong emotion, like sadness or even joy. Its a very ineffective method, since a lot of these substance are actually absorbed back from our tears after they've left the tear duct. However this is why people often feel calmer after they've cried...
There is another reason for us crying too. Its to show strong emotion. Since we are social animals, showing emotion is an important ability. Emotional crying is pretty much exclusive to humans, however I think one or two other animals like elephants and gorillas MIGHT also have the ability, however its not really been proven.
