Also asked, is the placenta fetal or maternal tissue?

At what week is the placenta fully formed?
This arrangement greatly increases the area of contact between the wall of the uterus and the placenta, so that more nutrients and waste materials can be exchanged. The placenta is fully formed by 18 to 20 weeks but continues to grow throughout pregnancy. At delivery, it weighs about 1 pound.
What are the three layers of the placenta?

The mother's blood does not normally mix with the baby's blood during the pregnancy, unless there has been a procedure (such as amniocentesis or chorionic villus sampling) or vaginal bleeding. During delivery, however, there is a good chance that some of the baby's blood cells will enter the mother's bloodstream.What is a Lotus baby?
Lotus birth (or umbilical cord nonseverance - UCNS) is the practice of leaving the umbilical cord uncut after childbirth so that the baby is left attached to the placenta until the cord naturally separates at the umbilicus.

Blood flow in the unborn baby follows this pathway: Oxygen and nutrients from the mother's blood are transferred across the placenta to the fetus through the umbilical cord. But most of this highly oxygenated blood flows to a large vessel called the inferior vena cava and then into the right atrium of the heart.Is there DNA in placenta?
The cells in the placenta, like all nucleated cells, contain DNA. The placenta is derived from fetal cells, with a contribution from the lining of the mother's uterus. Therefore the placenta has DNA from both the fetus and the mother.Does the placenta have nerves?
