The dead space refers to the air that exists in the airway but does not reach the alveoli, thus it does not participate in gas exchange. It includes the air from the nose to the terminal bronchiole. Alveolar dead space specifically refers to air within non-functional alveoli affected by disease or abnormalities. Therefore, option 3 accurately describes the concept of dead space.
