Processes of Respiration • Pulmonary Ventilation – Moving air into and out of the lungs • External Respiration – Gas exchange between the lungs and the blood • Transport – Transport of oxygen and carbon dioxide between the lungs and tissues • Internal Respiration – Gas exchange between systemic blood vessels and tissues What are the Functions of the Nose?
