Well, remember, the alveoli of the lungs are completely filled with the fluid. But as soon as the first breath takes place, all that air that rushes into the alveoli of that lung displaces and removes pushes all that fluid out of the alveoli. And this expands the alveoli. And by expanding the alveoli, that decreases the resistance and decreases the pressure inside the alveoli. So as soon as the first breath is taken, what happens is we have a decrease in resistance and so a decrease in pressure which takes place within our lungs and that eventually also takes place within our liver. So the liver begins to function following birth.
