Respiration is the mechanism the body uses to exchange gases between the atmosphere, blood, and cells. Respiration involves three processes: ventilation (the mechanical movement of gases into and out of the lungs), diffusion (the movement of oxygen [O2] and carbon dioxide [CO2] between the alveoli and the red blood cells), and perfusion (the distribution of red blood cells to and from the pulmonary capillaries). The normal rate and depth of ventilation is known as eup-nea.
