embryonic period
umbilical cord contains two arteries and one vein. umbilican vein carries pure blood to the fetal heart and umbilical arteries carry impure blood to the placenta of the mother.
The embryo gets its nutrition from the yolk sac, which is an early source of nutrients and blood supply. This provides essential nutrients for the embryo's development before the placenta and umbilical cord are fully formed.
It is the place where the umbilical cord connects the baby to the placenta. After the baby is born, the umbilical is cut off, eventually heals over and leaves the belly button.
After four weeks,the fertilized egg becomes an embryo.Its brain spine and limbs are forming and its heart will soon beat.At 12 weeks, the embryo is now a foetus.All its organs are formed;for the rest of the time before birth, it just grows.From 38 weeks the baby is ready to be born.It moves down into the pelvis.The baby is born through the privet
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.
No, belly buttons are formed during development in the womb as a result of the umbilical cord being removed after birth. They are not inherited but rather a scar from where the umbilical cord was attached to the fetus.
During pregnancy, the placenta is formed from cells of both the mother and the embryo. The placenta incorporates genetic material from the father through the embryo's cells, which contain genetic information from both parents. This allows the placenta to provide essential nutrients and oxygen to support the development of the baby throughout pregnancy.
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.

The placenta is the organ that nourishes the embryo during pregnancy. It is formed from the tissues of both the mother and the developing fetus and allows for the exchange of nutrients and waste products between the mother and the baby.
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.
The placenta is the organ formed by the mother's body during pregnancy to nourish the baby with oxygen and nutrients from the mother's bloodstream and to remove waste products from the baby's blood. It serves as a connection between the mother and the developing fetus.
