Respiratory System


The respiratory system is a complex system of organs and tissues that provide oxygen to the body and eliminate carbon dioxide. It is vitally important in maintaining homeostasis by regulating acid-base balance and pH.

The respiratory tract comprises the nose, throat (pharynx), windpipe (trachea), bronchi and lungs.
