Question
Chapter 44, Problem 2TY
Summary Introduction
Introduction: Ears are the auditory organ of the mammals. It consists of three compartments: the outer ear (only visible part), middle ear, and the inner ear. The outer ear helps in gathering of sound waves from the surrounding environment and sends it to the other parts.
