Tears are a by-product of a chemical produced by lacrimal glands, which are located superiortemporally to each eye, behind the upper eyelid. The lacrimal glands secrete lacrimal fluid which flows through the main excretory ducts into the space between the eyeball and lids. When you blink, the lacrimal fluid is spread across the surface of the eye. Lacrimal fluid gathers in the lacrimal lake, and is drawn into the puncta by capillary action, then flows through the lacrimal canaliculi at the inner corner of the eyelids through the nasolacrimal duct, and finally into your nasal passage. An excess of tears, as with strong emotion, can thus cause the nose to run.
Hope this helps to anwser your question.

Salt is an important component of our bodies. One of the reasons for this is that the sodium ions released when salt is dissolved in water serve as essential carriers of electrochemical signals that allow us to function in an integral way. Without signaling a body cannot remain alive.
Salt is found in our blood, in our cells, indeed in all parts that are wet. It is no surprise, therefore, that all secretions of water from our body are salty. This is true of perspiration, which performs an important role in maintenance of our body temperature and it is also true for tears from our eyes. Incidentally, our eyes do not water only when we are sad. A little secretion from our eyes is almost continuous. This is to keep our eyes clean. The fluid that wets our eyes, and sometimes comes out as copious tears also contains, besides salt, a chemical called Lysozyme, which destroys bacteria that might infect our eyes.
Tears also come to other animals and birds. Like they do for us, for them also they perform the functions of cleaning and protecting their eyes. For the ocean-going birds the tears are a bit oily to protect their eyes from salt spray!
It is interesting to realise that frequent blinking of our eyes serves the same function for eyes as the movement of windshield wipers on the front window of our car on a slightly wet day. A thin, uniform layer of the tear fluid allows us to see clearly. The more we learn about the control and maintenance systems of our bodies, the more are we impressed with their virtuous ingenuity. It is hard to believe that all this was a part of an original design. It is more likely that the incomplete and imperfect designs did not survive. All of us now living are the efficient survivors of a long chain of evolution.
