Oxygen moves into the blood because the partial pressure of oxygen is higher in air and lower in blood. Carbon dioxide moves out of the blood because the particle pressure of carbon dioxide is higher in blood and lower in air.

∙ 11y agookay, to put it simply, when oxygen from the air outside enters the human lungs it enters the numerous, one cell thick alveoli. these tiny air sacs are very thin, have a large surface area and also have plenty of capillaries surrounding them. This means that Diffusion of the oxygen from the alveoli into the bloodstream is very quick. As might be expected the exchange of CO2(the waste product of respiration) is just the reverse, cells to bloodstream to alveoli to the air outside.
hope this helps

Which substances are exchanged between the blood in the capillaries and the air in the alveoli?
Oxygen, carbon dioxide, and water are the substances exchanged between the alveoli (air sacs) and the capillaries in the lungs.
What gasses are exchanged in the lungs?
There are two main gasses that are exchanged in the lungs: carbon dioxide and oxygen. The lungs use tiny air chambers called alveoli to take in oxygen and let out carbon dioxide.
Where are oxygen and carbon dioxide exchanged in the lungs?
oxygen and carbon dioxide are exchanged in alveoli (singular alveolus).
The small air sacs in the lungs through which gases are exchanged are the?
Alveoli
The exchange of gasses is the function of the what?
alveoli.
What is the name of the movement of gasses in the alveoli?
,
Which site is the site where gases are exchanged?
alveoli
What are the small sacs in the lungs where carbon dioxide is exchanged for oxygen?
The humorus
Which 2 gases are exchanged at the surface of the air sac?
During photosynthesis, carbon dioxide and oxygen are exchanged. The plant uses the carbon dioxide for the photosynthesis and expels oxygen.
Where the carbon dioxide and blood exchanged in the body?
Alveoli
Gasses are exchanged in what blood vessel?
Capillaries.
Is gas exchanged in the pleura?
--it is in the alveoli where the exchange of gases occur.. :))
