Description

The human respiratory system (or ventilatory system) is the biological system that introduces respiratory gases to the interior and performs gas exchange. The anatomical features of the respiratory system include airways, lungs, and the respiratory muscles. Molecules of oxygen and carbon dioxide are passively exchanged, by diffusion, between the gaseous external environment and the blood. This exchange process occurs in the alveolar region of the lungs.
