Summary Introduction
Introduction:
The primary function associated with the respiratory system is breathing. It has many other purposes also such as air passage, exchange of gases, odor detection and sound production. Breathing occurs as inspiration and expiration cause the bulk flow of air to enter and exit the lungs.
