Diffusion in the Body
In the body, diffusion takes place in lots of places
...
The oxygen we inhale is exchanged for carbon dioxide in
tiny air sacs in the lungs
...
At the same time, oxygen diffuses from the lungs into the bloodstream
...
These blood cells move
the oxygen across the body where it diffuses into other cells requiring oxygen
...
They
send electrical signals by the diffusion of ions across their cell membranes
...
The cell maintains a negative electric charge by controlling which ions go in
and out of the membrane
...
Kidney membranes - The kidneys help maintain levels of molecules that the blood
needs or doesn't need through diffusion with its membranes
...
They also take urea, a
waste molecule, from the blood into their cells, which have a lower concentration of
urea
...
Dialysis, which is
the artificial regulation of kidneys with a machine, also relies on membranes to
regulate the levels of ions and other compounds that pass through the kidneys
...
Specialized cells in the small
intestine take up these nutrients
...
After these intestinal cells absorb the nutrients, they transfer them to
blood cells in vessels on the other side on the membrane
