If so, how does it get there?
If not, what stops the lungs from collapsing?
Is a baby's first breath an exhalation (waaaah) followed by an inhalation or is it an inhalation followed by an exhalation?
If it is an inhalation, what causes the baby to only inhale when it is out of an aqueous environment?
Have any babies ever drowned in the womb?
Is it the same for all mammals?
Any links to learn more would be appreciated.
