oxygen
Carbon dioxide is produced as a waste product of respiration, and is taken in the bloodstream to the capillaries outside the lungs, where the CO2 diffuses into the alveoli of the lungs.
Oxygen is the gas that passes from the lungs to the bloodstream.
Oxygen moves into the lungs to the alveoli in the lungs into capillaries into pulmonary veins to the heart then to arteries that go through the rest of the body.
When you inhale, air fills the alveoli and oxygen passes from the alveoli through a semipermeable membrane and into the capillaries, leading into the bloodstream. During the same process, carbon dioxide is outgassed from the blood to the alveoli When you inhale, air fills the alveoli and oxygen passes from the alveoli through a semipermeable membrane and into the capillaries, leading into the bloodstream.

The alveoli and capillaries in the lungs pass oxygen to the blood. Both have very thin walls, which allow the oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.
Oxygen
Carbon dioxide is exhaled
The blood passes through tiny capillaries that lie in close proximity to the alveoli in the lungs. This is where the gas exchange takes place.
blood, at first it is deoxygenated but by the time it leaves the lungs it is full of dissolved oxygen
Oxygen enters your nose,then goes through the trachea,to the bronchi,and last to your lungs.
In the alveoli of the lungs. This is where oxygen diffuses from the lungs into the bloodstream and carbon dioxide diffuses out of the bloodstream and into the lungs.
In the alveoli of the lungs, where it passes into the blood capillaries which surround them.
