sometimes a placenta can have abnormal growth and attachment to the uterus (the growth can penetrate deeply into the muscle of the uterus) and this can cause the placenta to stay attached. This is not the norm. Usually a placenta is superficially attached to the muscle of the uterus and easily detaches after a baby is born
It is not possible for a baby to be born without an umbilical cord. It would not survive in the womb without a placenta delivering its needed nutrients.
True
Placenta gets damaged by toxins like alcohol or chemicals from cigarettes. This leads to prevention of blood from mixing and/or an affected child by transportation of toxins from mother to child.
it would not be heathly
If the placenta don't function the embryo will die.
The orbiter would detach and land in the ocean shortly after take off.
If the afterbirth, or placenta, comes out before the calf during calving in a cow, it could be due to a premature detachment of the placenta from the uterus. This can happen if there are issues with the placenta or uterus, leading to complications during the birthing process. It is important to consult a veterinarian in such situations to ensure the health and safety of the cow and calf.
In normal pregnancy, the placenta is located at the top of the uterus, above the baby. So the placenta would be delivered after the baby. Placenta Previa is when the placenta forms in the lower part of the uterus, partially or totally covering the opening of the cervix. In this condition, the placenta would be delivered first during a vaginal delivery. Women with Placenta Previa require delivery by cesarean section, because as soon as the umbilical cord reaches oxygen, the baby will automatically use his lungs to breathe. So, if the placenta were to be delivered first, the umbilical cord would reach oxygen and the baby would be in the womb suffocating because the lack of oxygen.
The placenta detaches from the uterine wall during labor because of hormones that are released as well as the force of contractions. If it is left inside it can cause at least two major problems: 1. The placenta being inside the uterus would prevent it from contracting as it naturally does after the baby is born. Without this contraction, the site where the placenta separates from the wall of the uterus during labor would not be able to stop bleeding (think of the contraction as applying pressure to this wound). This can lead to postpartum hemorrhage and death of the mother. 2. Assuming that the mother does not have a hemorrhage and the placenta stays inside her uterus, it would begin to decompose because it no longer has a blood supply. Think of this as like any meat: it's fine when it's on the animal, but once you take away the blood supply it begins to die. This would in turn cause an infection that, if not treated, would likely kill the mother.
This condition is called Placenta Previa. With placenta previa, the placenta grows on the lower part of the uterus partially or totally covering the opening of the cervix. The placenta should form at the top of the uterus, above the baby. With a normal pregnancy, the baby would be born first, then the placenta. With placenta previa, the placenta would be delivered first. Women with placenta previa require a c-section because as soon as the umbilical cord comes into contact with oxygen, the baby will automatically breathe with his lungs. Delivering the placenta first puts the baby at risk of suffocation in the womb.
They would slowly remove the placenta (cord) by pulling it out with a clamp in a certain way after the delivery of the baby.
