Additionally, what triggers a baby, once exiting the womb, from taking its first breath?
In: Biology
The lungs are filled with amniotic fluid, and there is no distress from it. When the baby is being born, between the head being delivered, and the restitution of the head and shoulders, the chest gets a really good squeeze, which usually forces lots of the fluid out, and prepares the lungs to start gas exchange.
