How does oxygen diffuse within the lungs? a. it diffuses from the capillaries into the veins. c. it diffuses from the alveoli into the blood. b. it diffuses from the arteries into the capillaries. d. it diffuses from the blood into the alveoli.

The answer should be C, It diffuses from the alveoli into the blood.

Alveoli, also called the air sac, is the place where the oxygen we breathed in is exchanged with carbon dioxide that our body produces. Oxygen is passed into the blood in the capillaries through the process of diffusion, while carbon dioxide is diffused from the blood back to the alveoli, so that we can exhale the carbon dioxide after that.

Both a and b are not right because when we breathe in, the oxygen travels from the trachea to the bronchi, to the bronchiole, and to the alveoli, instead of directly into blood vessels like arteries, capillaries, or veins. d is also not right because the direction is wrong.

Therefore, your answer should be C.

Oxygen diffuses by from the alveoli into the blood.

mountains can affect the climate of nearby lands. in some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. much of airborne moisture falls as rain on the windward side of mountains.
