The endometrium begins to form shortly after the fertilized egg (blastocyst) implants into the uterine wall (endometrium). This typically occurs 3-4 days after fertilization. After implantation, the endometrium is called the Decidua, and basalis is the portion directly under the blastocyst. The Basalis joins the chorionic villi to make the placenta.

What part of the uterus does the placenta attached to?
The placenta will be attached to the uterus, but it is not part of it. The uterus is a muscle and is part of basic female human anatomy. The placenta is an organ which is formed after conception.
During which prenatal period are the placenta and umbilical chord formed?
embryonic period
What is the organ formed by the mother's body to nourish the baby and excrete waste products?
The placenta.
What is a placenta formed from?
The placenta is developed during pregnancy from the implantation of a blastocyst. The blastocyst creates the outer layer of the placenta. This continues to developed into two more portions and then develops an outer protective layer. The placenta grows throughout the entire pregnancy.
Which foetal membrane takes part in the formation of placenta?
placenta is a complex structure formed by the process of trophoblastic cells (chorionicfondosum)and part of uterine endometrium called decidua basalis
What is placenta and mention its role?
It is the the biological mass which is formed in a pregnant woman's womb which feed the embryo.
How waste and products transferred after the placenta is formed?
it goes to the mothers blood hope this helps! lololololol
Why is the placenta called the baby's 'life-support' system?
THE PLACENTA is visibly formed at 12 weeks gestation. At about this point, the placenta takes over a very BIG job from moms hormones. The placenta is now 100 percent responsible for nourishing the fetus. The placenta attaches to the baby at the umbilical cord, or the "belly- button." The placenta is called the babys life support system because it provides everything the fetus needs to stay alive until birth. Without the placenta, the baby would die.
Where do the nutrients used by the zygote between fertilization and implantation come from?
The nutrients used by the zygote between fertilization and implantation come from the newly formed placenta. The placenta is what provides nourishment to the developing fetus.
What structure carries blood between the fetus and the placenta?
Umbilical Cord
What is the medical term meaning abnormal implantation of the placenta?
Placenta previa, placenta accreta, placenta increta, and placenta increta are all conditions stemming from abnormal implantation of the placenta.
What is the membrane that forms the embryonic side of the placenta?
The placenta is completely formed by 10 weeks, by the joining of the decidua basalis (maternal side) and chorionic villi (fetal side). The chorion and amnion are the placental membranes. The Chorion is the membrane furthest from the embryo, and the amnion in the inner layer that is closest to the embryo.
