What layers must oxygen and carbon dioxide pass through as they exchange between blood in capillaries and the air in the alveoli of the lungs?
Oxygen and carbon dioxide pass across the Alveolar-capillary barrier. This is the barrier that separates the air sac in the lung (the alveoli) from the miniscule blood vessel (the capillary). The barrier is extremely thin - a hundred times thinner than a regular piece of paper. Follow the Related Links below to view a Wikipedia article on this subject.

What principle causes the exchange of oxygen and carbon dioxide between the capillaries and the alveoli?
diffusion
Which substances are exchanged between the blood in the capillaries and the air in the alveoli?
Oxygen is exchanged from the air in the alveoli into the blood in the capillaries, while carbon dioxide is exchanged from the blood in the capillaries into the air in the alveoli during the process of respiration.
What passes between alveoli and capillaries?
Capillaries are tiny thin-walled blood vessels that connect the smallest arteries and veins and allow the exchange of nutrients and waste between the blood and tissues. Oxygen and carbon dioxide are exchanged between the circulatory and respiratory systems; oxygen diffuses from the lungs into the bloodstream and is transported by erythrocytes (red blood cells) throughout the body. Carbon dioxide diffuses out of the blood into the alveoli and goes the reverse direction through the respiratory system and out the nose.
Exchange of gases in the lungs takes place between the alveoli and?
When we exhale /blow out we push out all the carbon dioxide in our lungs!
How does exchange of gases take place between the walls of the alveoli and the capillaries?
oxygen and carbon dioxide take place
Where does the exchange of oxygen and carbon dioxide between the air and blood occur in humans?
The exchange of oxygen and carbon dioxide between the air and blood occurs in the alveoli of the lungs. Oxygen from the air diffuses into the blood in the capillaries surrounding the alveoli, while carbon dioxide from the blood diffuses into the alveoli to be exhaled.
Why do capillaries cover the alveoli?
Capillaries cover the alveoli in order to maximize the area for gas exchange between the lungs and the blood. Carbon dioxide is released from the blood through the capillary walls and into the alveoli, while oxygen is picked up from the alveoli through the capillary walls and into the blood.
Where does the diffusion of oxygen and carbon dioxide occur?
In the lungs, the diffusion of oxygen occurs from the alveoli (air sacs) into the blood capillaries, while the diffusion of carbon dioxide occurs from the blood capillaries into the alveoli for exhalation. This exchange process is facilitated by differences in partial pressures of oxygen and carbon dioxide between the air in the alveoli and the blood in the capillaries.
Exchange of gases occurs between cappilaries and what?
To allow Oxygen to travel to every Cell in a living organism there is a gas exchange between nearby Capillaries and the cells of that organism.The same exchange works the other direction to take away waste products of cell living
By what process does the exchange of oxygen and carbon dioxide take place?
capillaries and the alveoli
In which structure does gas exchange occur?
Gas exchange occurs in the alveoli of the lungs. These tiny air sacs are surrounded by capillaries where oxygen from the air can enter the bloodstream and carbon dioxide can be removed from the blood.
Where does the exchange of oxygen carbon dioxide in the blood happen?
The exchange of oxygen and carbon dioxide in the blood occurs in the capillaries surrounding the alveoli in the lungs. Oxygen diffuses from the alveoli into the blood, while carbon dioxide moves from the blood into the alveoli to be exhaled.
