Does the placenta help form the umbilical cord?
No, they are not. The umbilical cord is an actual cord that connects the baby to the placenta. The placenta is the lining of the uterus that is developed over the course of the pregnancy. The placenta is a "filter" through which the baby's food and oxygen is delivered via the umbilical cord. Once the baby is born, the umbilical cord is clipped and severed. The final, 3rd stage of labor, is the passing of the placenta. That happens 15-30 minutes after the baby is born. The placenta is then checked thoroughly, to ensure that is in intact, and that no pieces are left behind in the uterus. This is VERY important, because if any of the placenta is left in the uterus, it will cause an infection, high fever, can lead to infertility. If not removed, the outcome can be lethal.
How does ex utero intrapartum treatment work?
A cesarean section procedure leaves the umbilical cord intact so that the placenta continues to sustain the fetus. After the air passage is cleared, the umbilical cord is cut and the newborn can breathe.
How do you breathe under water when you are first born?
You don't. Humans, of any age, can't breathe underwater w/o the aid of machines. But babies have two things going for them. First it's something called the dive reflex that'll have them hold their breath. Secondly, if they're actually born under water, they won't need to breathe as long as the umbilical cord and the placenta is intact. They've gotten their oxygen from the blood from the mother through the umbilical cord, since conception, and a few minutes longer will work just fine.

Why is circulation to the lungs bypassed in fetal pigs?
It is bypassed because there is no need for the blood to go to the lungs and get "pick up" if the pig is dead.

Can the spinal cord work separate of the brain?
Yes the spinal cord can work without the brain.
Is it dangerous if placenta does not come out?
If the placenta does not come out then the doctor has to inject you with hormones to help you pass it out. If that still doesn't work then the doctor has to manually take it out, because if the placenta stays inside of you, it poses a health risk to the mother.
How does the fetal circulation work?
The blood goes from the mother to the placenta where gas exchange occurs to the fetus. From the placenta the blood goes into the arterium and to the body of the fetus.
