Does The Mfc7440n Print Color When Is The Placenta Formed And Meanwhile How Does The Baby Survive?
When is the placenta formed and meanwhile how does the baby survive? - does the mfc7440n print color
It is said that the placenta in full by 20 weeks of pregnancy is formed. Meanwhile, as the fetus to live without them? 20 weeks ago
Moreover, it is logical that stimulation at 20 weeks, because in just 7 days, part of the chorionic villa (from the placenta), the release of hCG to the corpus luteum.
More likely not to 7 days to 20 weeks.

The placenta begins to form on day 4.
The fertilized egg begins to divide and day 4, is classified as a blastocyst. The party is the fetus, the rest of the placenta.
On Day 6, the blastocyst has attached to the uterus. Here are eroded its way into the uterus' lining (endometrium), which begins the formation of the placenta.
Meanwhile, the embryo in the same way a chick is not - that their own yolk sac in the meantime has nourished. These nutrients in the placenta is established.
The placenta is formed and fully functional at the time the embryo as a fetus - of 8 weeks. Week 8 and after the baby is fed by the right of the placenta until birth.
The baby begins with a single cell, binds rapidly to the uterine lining. He takes nutrients from the uterine wall, and I suspect that the placenta is not complex structure liketh necessary if the fetus is so small. Nutrients can easily through areas that only a few cells thick, without the need for complex pipelines, which are now in a closed loop system.
I suspect that hCG of cells that is ultimately released the placenta.
I'm not sure, though.
