Were does the placenta form

Answer 1

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

Answer 2

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.

Answer 3

- 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.

Answer 4

The placenta was form from decidua basalis.

Answer 5

In the amniotic sac which is inside the uterus.
