NO
Fetal mammals don't "eat" anything; they get their nutrients through the placenta.
No. seahorses are ovoviviparous...meaning they produce eggs but their eggs are in the placenta rather than being outside the body!
Placenta previa, placenta accreta, placenta increta, and placenta increta are all conditions stemming from abnormal implantation of the placenta.
Placenta comes out after each kitten.
Before placental development the conceptus gets nutrition from uterine secretions. After placentation nutrition comes from the mare via the placenta.
The umbilical cord is attached to the placenta and the placenta is attached to the wall of the uterus
In horses, the placenta serves as the connection between the mare and foal, providing nutrition and oxygen to the developing fetus and removing waste products. It also acts as a protective barrier, preventing the mare's immune system from rejecting the foal.
Yes. But the movement is relative. Placenta does not change the position. But lower placenta may move up. So that placenta previa may become normal placenta.
Yes kangaroos have a placenta.
Placenta Previa
No, a placenta attached to the front and back of the uterus is not considered placenta previa. Placenta previa specifically refers to a condition where the placenta partially or completely covers the cervix. In contrast, a placenta that is attached to the front (anterior) and back (posterior) of the uterus may be referred to as a bilobed or multilobed placenta, but it does not indicate previa unless it is obstructing the cervical opening.
