What special characteristic of the respiratory membrane facilitates gas exchange? the large surface area of the combined alveoli facilitates gas exchange the presence of alveolar macrophages and mucus keep the alveoli clear and reduce membrane thickness cartilages in the walls of the alveoli hold the alveoli open to increase lung volume and surface area smooth muscles in the walls of the alveoli hold the alveoli open to increase lung volume and surface area
