Eyes are organs of the visual system. They provide animals with vision, the ability to receive and process visual detail, as well as enabling several photo response functions that are independent of vision. Eyes detect light and convert it into electro-chemical impulses in neurons. In higher organisms, the eye is a complex optical system which collects light from the surrounding environment, regulates its intensity through a diaphragm, focuses it through an adjustable assembly of lenses to form an image, converts this image into a set of electrical signals, and transmits these signals to the brain through complex neural pathways that connect the eye via the optic nerve to the visual cortex and other areas of the brain.
Cold and flu season, allergies, and even inhaling an irritant like smoke or perfume can cause an unpleasant coughing fit. Coughing is the body's way of getting rid of anything that's irritating the throat or lungs. It's estimated that coughs can be expelled from the mouth at speeds of up to 100 mph (via Penn Medicine)
