Ear wax

Earwax is produced by glands in the ear canal. Although scientists are still not completely sure why we have earwax, it does trap dust and other small particles and prevent them from reaching, and potentially damaging or infecting the eardrum. Normally, the wax dries up and falls out of the ear, along with any trapped dust or debris. Everyone makes ear wax, but the amount and type are genetically determined just like hair color or height. Smaller or oddly shaped ear canals may make it difficult for the naturally occurring wax to get out of the canal and lead to wax impactions.
