The placenta develops in the uterus after the zygote has implanted in the Uterine wall. This wall develops into the placenta during pregnancy. If implantation does not occur the wall will be sloughed off in the next menstrual cycle
whereever the embryo implants in the wall of the uterus. it implants completely into the endometrium but also extends a bit into the myometrium. it's usually in the posterior wall of the uterus. if the embryo implants in other places, like the fallopian tube or abdominal cavity, the placenta will still form and it can be fatal to the mother.
- Development of the placenta and fetus is a continuous process that begins at the time of fertilization. Four days after fertilization, the morula (a solid mass of blastomere cells) enters the uterus. As uterine fluid penetrates its outer layer (the zona pellucida), a blastocyst with a cavity is formed. Further ingress of fluid results in separation (hatching) of the expanded blastocyst into two parts: * Inner cell mass - a group of blastomeres which form the embryo * Trophoblast - a thin outer cell layer of blastomeres which form the placenta and fetal membranes The blastocyst is bathed in uterine secretions that provide the embryo with oxygen and metabolic substrates. However, this soon becomes inadequate for further development and the embryo must then implant in the uterine wall. The progenitor villous trophoblast cell is the stem cell of the placenta.
The placenta was form from decidua basalis.
In the amniotic sac which is inside the uterus.
Normally, the placenta should develop relatively high up in the uterus, on the front or back wall.

The umbilical cord connects to the Placenta once it is in form to attach
e is no known cause of a battledore placenta. It is simply the way the cord grows out of the placenta, there is also nothing that can be done to change the pattern of growth once it begins to form. It can however be detected by ultrasound examination of the placenta.

The embryo attaches to 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.
You can absolutely eat your placenta. Even better, you can sometimes find people who will dehydrate and encapsulate your placenta so you can take it in pill form. It is a wonderful way to return nutrients to your body and stabilize post partum hormones. Just tell the nurses beforehand that you want your placenta saved!!
