Question

how does oxygen move from the alveoli to blood

Answer 1

Hey mate here is your answer》》

The exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.

Oxygen and carbon dioxide move from where there is a large concentration to where there is a lower concentration. This movement is called diffusion. Oxygen diffuses from the alveoli, into the blood in the capillaries. Similarly, carbon dioxide from the blood moves out of the capillaries into the alveoli.
