made by glands located above the eyes. In fact, the cells of these glands filter the blood and secrete a liquid that contains oxygen, antibacterial agents and other substances. Each time the eyelid passes over the eye like this, it deposits a small amount of liquid on the eye. In this way, the eye does not dry out, it is protected against bacteria by the antibacterial agents and the oxygen contained in the liquid feeds the cells of the cornea. Since the tap is always open, a small conduit allows the tropline to be channeled towards the false nasals. So what happens now when we have a big pain? Well, the emotional shock stimulates the lacrimal glands which start to produce more liquid than in normal time. The flow is not enough, well, the tropline of the weapon passes over the edge. So you will surely have noticed, often, after crying a good blow, we feel better. It's quite normal. Indeed, tears evacuate the stress hormones which initially circulate in the blood vessels.
