Q:When we cry why water is coming?
The human body produces tears by stimulating two glands situated above each eye, behind the upper eyelids. These lacrimal glands are responsible for excreting lacrimal fluid.
The excess tears collect in an area known as the lacrimal lake, where they will eventually be drawn into a small opening called the lacrimal duct. If the duct becomes overwhelmed or blocked, however, the excess may spill out of the lower eye. The lacrimal duct drains into the nasalacrimal duct, where the tears may either drain into the throat or nasal passages.
The production of tears is essentially semi-automatic. The lacrimal glands routinely produce a small amount of liquid in order to keep the eyes lubricated and free of irritants. If a specific irritation, such as the gas from a raw onion or cigarette smoke, reaches the eyes, then the brain can send out a signal for the lacrimal glands to produce more.
