Why do we have earwax?

Show answer & explanation

Answer: Protects ear from dust and germs

Protects ear from dust and germsCorrect! Earwax (cerumen) is produced by glands in the ear canal. It traps dust, dirt, and germs, preventing them from reaching the eardrum. It also keeps the ear canal moisturized and has antibacterial properties.

Leftover from ear developmentWrong. Earwax is actively produced throughout life, not a leftover from development. It serves an important protective function.

Result of ear infectionsWrong. Earwax is normal and healthy, not a result of infection. It actually helps prevent infections by trapping harmful particles.
