It’s on the baby’s stomach. How does it make air get into its lungs? The placenta is filled with fluids and stuff, so how does the baby breathe with a thing connected to it’s stomach? It also provides food, but how?

It’s not like an air tube. Basically oxygen and nutrients are carried from the mother to the baby via the blood vessels in the umbilical cord. You don’t start “breathing” until you are born.
