Answer

The correct answer would be auricle and auditory canal.

The auricle or pinna is the externally visible part of the ear. it is mainly composed of cartilages and integuments. It is connected to the surrounding parts with the help of muscle and ligaments.

It helps in focusing the most of the sound vibrations towards inside the ear.

It opens into the auditory canal which serves as the pathway for sound waves to the inner ear (tympanic membrane).

The outer ear consists of two things and they are the auricle and the ear canal , which is also called the auditory canal.

The auditory canal  goes from the outer ear to the middle ear.

The auricle is what we see of the ear...the physical part of the ear. It can be called the pinna as well.

I hoped that this helped and good luck.
