where does wax in your ears come from
Earwax Earwax consists of shed skin cells, hair, and the secretions of the ceruminous and sebaceous glands of the outside ear canal.[2] Major components of earwax are long chain fatty acids, both saturated and unsaturated, alcohols, squalene, and cholesterol.[2] Excess or compacted cerumen can press against the eardrum or block the outside ear canal or hearing aids, potentially causing hearing loss.
Eustachian tube In humans and other land animals the middle ear (like the ear canal) is normally filled with air. Unlike the open ear canal, however, the air of the middle ear is not in direct contact with the atmosphere outside the body. The Eustachian tube connects from the chamber of the middle ear to the back of the nasopharynx.
