The respiratory system is a biological system made up of specific organs used for gas exchange in animals and plants. The anatomy and physiology that make this system vary greatly. It depends on the size of the organism, the environment in which it lives, and it’s evolutionary history. Designed to pull oxygen from the air through the lungs, it enters the bloodstream and expels carbon dioxide. Take a deep breath and take the quiz.
