Question

write a short note diffusion of respiratory gases in alveoli

Answer 1

Hey mate, here is your answer ===
Diffusion means the movement of the particles from its higher concentration to its lower concentration.
So the oxygen is more in liver and less in alveoli while carbon dioxide is more in alveoli and less in liver so they just exchange the gases.

Hope it helps u dear :)

Answer 2

Answer:

The walls of the alveoli share a membrane with the capillaries. That's how close they are. This lets oxygen and carbon dioxide diffuse, or move freely, between the respiratory system and the bloodstream. Oxygen molecules attach to red blood cells, which travel back to the heart
