Descrição:

I am now inhaling and exhaling some liquid, I think it's called Amniotic fluid. I'm having a hard time doing this, but it will get better, right? By the day, it is getting easier, but I'm not sure if I will get asthma. cnx.org/contents/65bbf29b-b710-49fa-aab3-d89137a61a0f@5/embryonic-development-of-the-respiratory-system.
