The document matches components of the human ear to their functions: the outer ear captures sound waves and directs them to the eardrum, the middle ear contains the eardrum and delicate bones that transmit vibrations from the eardrum to the inner ear, and the inner ear contains the cochlea with delicate hairs that convert vibrations into electrical impulses and is where a fluid-filled structure is located.
