Membranes have a total thickness of only 0.5-micrometers, in contrast to the 7.5-micrometer diameter of the erythrocytes (blood cells) that pass through the capillaries. The respiratory membrane, also called the respiratory surface, is made of the alveolar epithelial cell and the pulmonary capillary endothelial cell, and this structure helps exchange the gases of carbon dioxide and oxygen. The respiratory membrane plays a key role in exchanging gases within the lungs. This membrane also helps bring oxygen into blood and remove carbon dioxide.

The respiratory membrane, the only barrier between the oxygen-rich air within the alveoli and the carbon dioxide-rich blood carried by the capillaries, is about 0.5μm thick as opposed to the 7.5μm-diameter of blood cells traveling through the capillaries .
The respiratory membrane is very thin, as it consists of only two cells - that is, the alveolar epithelial cell
The arrows in this diagram demonstrate the movement of gases across the respiratory membrane. Oxygen diffuses from the alveoli to the blood in the capillary,
The respiratory tract is lined by a smooth membrane called a mucous Oxygen is passed from the alveoli into the blood stream and carbon dioxide is passed
The main function of the lungs is oxygen transport from the atmosphere into the blood circulation, while it is necessary to keep the pulmonary tissue relatively
The PLEURA are the two membranes, actually, one continuous one folded on itself, that surround each lobe of the lungs and separate your lungs from your chest
Water vapor pressure and carbon dioxide in the lung displace oxygen. Diffusion of gases across the many layers of the alveolar-capillary membrane is the
