Answer 1

Diffusion is the net movement of molecules or atoms from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in chemical potential of the diffusing species

so ur answer in ur text ---

Oxygen moves from higher concentration (in the air sac) to lower concentration (into the blood). diffusion happen
