The membrane of the alveolus, the air sacs in the lungs where this process takes place, is only one cell thick. The wall of the capillary running adjacent to the alveolus is also one cell thick, so the gases are exchanged between the alveolus and the capillary cell membranes.

What cell is the Cell Membrane in?
The respiratory membrane consists of the epithelial cells of the alveolus, the endothelial cells of the capillary, and the two fused basement membranes of these layers.Gas exchange occurs across this respiratory membrane.
What is required in all living things in order for gas exchange to occur?
In any living organism that needs to breath, the only thing consistently required for life is the presence of moist membranes. The movement of oxygen and carbon dioxide across the membranes between the environment and the respiratory surface occurs by diffusion. Respiratory surfaces are generally thin and, since living animal cells must be wet in order to maintain their plasma membranes, these respiratory surfaces must be moist.
What system provides gas exchange between blood and air?
Capillary system is where gas exchange occurs
Oxygen and carbon dioxide are exchanged in lungs and through all cell membranes by?
Gas exchanges occur by simple diffusion through the respiratory membrane -- oxygen passing from the alveolar air into the capillary blood and carbon dioxide leaving the blood to enter the gas-filled aveoli.
What connection between alveolus and visceral pleura?
The aveoli are microscopic pockets in the lung where gas exchange occurs. The visceral pleura is a membrane that covers the entire lung. There is no connection except that they both involve the anatomy of the lung.
What cell is the Cell Membrane in?
The respiratory membrane consists of the epithelial cells of the alveolus, the endothelial cells of the capillary, and the two fused basement membranes of these layers.Gas exchange occurs across this respiratory membrane.
Where does gas exchange occur in the human respiratory system?
Gas exchange does not occur in the respiratory tract, it occurs in the alveoli.
What is the elastic unit of the respiratory system where gas exchange occurs?
Alveoli is where gas exchange occurs.
Where is the respiratory surface?
A respiratory surface is located anywhere in an animal or human being where gas exchange occurs. A respiratory surface is located anywhere in an animal or human being where gas exchange occurs.
Where in the respiratory tract does gas exchange occur?
The gas occurs by simple diffusion through the cells.
Why are the alveoli sometimes called respiratory membrane?
The alveoli are sometimes refer to as the respiratory membrane. This due to the transfer of gases that occurs between the epithelium (the membrane) and the capillaries (the blood). When Oxygen and carbon dioxide transfer across this membrane through diffusion Oxygen goes into the blood and Carbon dioxide is diffused out into the Alveoli.
What do the respiratory and the circulatory systems do together?
Working together, the respiratory and circulatory systems perform gas exchange from the blood to the lungs. This exchange occurs at the alveoli.
Where in your respiratory system does the exchange of O2 happen?
Gaseous exchange occurs in the alveoli (singular = alveolus) of the lungs.
A basement membrane occurs between?
a basement membrane occurs between the epithelial tissue and the connective tissue
What part of the respiratory tract is not exchange gases?
Gas exchanges occurs in the "alveoli".
What is the respiratory organ of earthworms?
The earthworm has no special respiratory organs. Gaseous exchange occurs through moist skin by diifusion.
Where in the lungs does gas exchange?
Gas exchange occurs across the respiratory membrane of the alveoli; however, the short answer is simply alveoli
