Verified step by step guidance

Understand the anatomy of the ear: The ear is divided into three main parts - the outer ear, the middle ear, and the inner ear.

Identify the components of the outer ear: The outer ear consists of the pinna (or auricle) and the auditory canal.

Recognize the function of the pinna: The pinna is the visible part of the ear that is outside the head. Its primary function is to capture sound waves from the environment and funnel them into the auditory canal.

Differentiate between the pinna and other parts of the ear: The auditory canal carries sound waves from the pinna to the eardrum, the cochlea is part of the inner ear responsible for converting sound waves into nerve impulses, and the auditory nerve transmits these impulses to the brain.

Conclude that the pinna is the part of the ear that acts as a funnel for sound from the outside world, directing it into the auditory canal.
