this is the case with
gases
and for particles
dissolved
in
solutions
particles diffuse
down
a concentration gradient, from an area of
high
concentration to area of
low
concentration
the capillaries have
lower concentration
of
oxygen
than the
alveoli
this results in diffusion of
oxygen
, from an area of
higher
concentration in the
red blood cells
(
capillaries
)
