simple questions need simple answers
----> humans have emotion thats why theyre cry XD.
crying or weeping, is increased lacrimation due to strong emotional stress, depression or physical pain. This practice is not restricted to negative emotions; many people have been known to cry when extremely happy or when they are laughing. In humans, emotional tears can be accompanied by reddening of the face and sobbing — cough-like, convulsive breathing, sometimes involving spasms of the whole upper body. Tears brought about by emotions have a different chemical make up than those for lubrication. The limbic system is involved in production of basic emotional drives, such as anger, fear, etc. The limbic system also has a degree of control over the autonomic system. This is more specifically the hypothalamus. It is the parasympathetic system that controls the lacrimal glands. Acetylcholine is the neurotransmitter specific to both the nicotinic and muscarinic receptors. It is when the receptors are activated that the lacrimal gland is stimulated to produce tears.
A release of fluid, like sweating i guess! The psychological purpose is to release emotion and show it physically, whether tears or joy or sadness.
I do not if it is much use? If you are being attacked by a Tiger all the crying in the world will not help at all. It will eat you tears and all.

tears are cleansing water, they clean your eyes and clean you wounds as you feel them aching. crying is to frowning as laughing is to smiling, its an extreme emotion expressed to comfort oneself.
I personally think that a good cry cleanses the spirit and allows you to get through your grief a bit quicker because you are getting those feelings out.
