Final answer:
Earwax is produced by ceruminous glands in the ear canal to protect the inner ear from dust and particles.
Step-by-step explanation:
Earwax is produced by ceruminous glands. These glands are found in the ear canal and are responsible for producing a waxy substance called cerumen, commonly known as earwax. Ceruminous glands help to protect the ear canal by trapping dust, dirt, and other particles, preventing them from reaching and damaging the delicate structures of the inner ear.
