the air goes into your lungs. In your lungs there are billions of tiny air sacs. Surrounding each air sac is a network of blood capillaries. The air sacs and the blood capillaries are separated by a thin membrane. Across this membrane the air sacs give the blood capillaries oxygen and they blood capillaries give the air sacs carbon dioxide. We breathe out this carbon dioxide!
in the micro air sacs
The lungs are the primary organs that fill blood with oxygen. Oxygen from the air is inhaled into the lungs, where it moves into the bloodstream through tiny blood vessels called capillaries surrounding the lungs' air sacs.
Tiny air sacs where the exchange of gases between air and blood takes place are located in the lungs. These air sacs are called alveoli and are surrounded by capillaries where oxygen from the air enters the blood and carbon dioxide exits the blood into the air.
alveoli. These are tiny air sacs in the lungs where oxygen from inhaled air enters the bloodstream and carbon dioxide from the blood is expelled into the lungs to be exhaled.
Because the air sacs carry oxygen to the blood!
Oxygen moves into the capillaries from the air sacs. Carbon dioxide moves out the the capillaries into the air sacs.

true
Oxygen enters the blood stream through the air sacs in you lungs.
In the air sacs oxygen and other gases are stored and separated to be put into the blood stream.
Oxygen enters the pulmonary blood in the capillaries of the alveoli -- the air sacs of the lungs.
oxygen that is inhaled into the lungs is diffused through the small air sacs, called alveoli, into the bloodstream.
in the micro air sacs
The air sacs (alveoli) have a very large total surface area and a very good blood supply. There is an exchange of gases between the air sacs and their surrounding capillary blood vessels. Oxygen diffuses from the air sac into the blood. Carbon dioxide diffuses from the blood into the air sac.
