If I'm not wrong, the O2 is carried from your lungs by red blood cells, then is passed to the muscles which need it through the walls of the blood vessels, while they take CO2 from the muscles to bring it back to the lungs to expel.
So... it occurs through the bloodstream and the walls of the blood vessels (capillary vessels etc.)
Lungs
More specifically in pulmonary capillaries.
Pulmonary capillaries lie next to the alveoli membranes. CO2 diffuses from the blood within the pulmonary capillaries and enter the alveolar space while O2 from alveoli diffuses into the blood.
the exchange of oxygen and carbon dioxide occurs at the level of the?
of the lung
The respiratory system uses the diffusion of oxygen and carbon dioxide. You inhale the oxygen which goes through the alveoli and thew capillaries in the lungs and you exhale it through the same section you inhale from. Therefore they diffuse together.
No According to my utas quiz :)
Diffusion
Carbon dioxide is the product; oxygen and carbon are the reactants.
When carbon reacts with oxygen to form carbon dioxide, carbon dioxide is the product of the reaction.
Little sacs called alvioli-- in the lungs.
The exchange of oxygen and carbon dioxide occurs through the mechanism of diffusion. The gases diffuse across the thin walls of the capillaries, both in the body tissues and in the capillaries surround the alveoli in the lungs.
Capillaries exchange food, oxygen, and carbon dioxide.
It is the process of simple diffusion. The movement of oxygen from a high level (in the air) to a lower level (in the blood). The opposite occurs for carbon dioxide which is higher in the blood but lower in the air.
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.
No. It depends on the concentration of carbon dioxide in the alveoli and the blood. The concentration of carbon dioxide in the capillaries of the alveoli is higher than the concentration of carbon dioxide in the air, so carbon dioxide in the capillaries of the alveoli diffuses out of the capillaries into the alveoli of the lungs and is exhaled.
oxygen and carbon dioxide
Oxygen (O2) goes to ur blood and carbon dioxide (CO2) goes back to the atmosphere.
That is a natural physiological process that occurs in the lungs. It is usually referred to as gas exchange, where the blood is enriched with oxygen as it looses most of its load of carbon dioxide.
