Final answer:

In the lungs, oxygen diffuses from the alveoli to the nearby capillaries, facilitated by pressure gradients.


Explanation:

Oxygen diffuses from the alveolus to the capillary, where it enters red blood cells. This occurs due to pressure gradients, with a higher oxygen concentration in the alveoli than in the blood of the capillaries surrounding them.
