It is connected to your baby through the umbilical cord. When you are four weeks pregnant, the blood flow between you and the embryo begins to take place. The umbilical cord and the placenta bring to your baby oxygen and nutrients necessary for its development.
How the placenta is it made? It is a unique, temporary organ. the placenta has the particularity of being made up of an embryonic part, the trophoblast, and a maternal part, the endometrium. Giving a layer of extraembryonic mesoderm on its inner side, the trophoblast provides the chorion.
the placenta is formed from two adjoining membranes: the decidua, part of the maternal uterine lining having undergone various transformations and the embryonic trophoblast comprising many folds called “villi of the chorion”.
During the first weeks, theembryo feeds thanks to the yolk sac and the nutrients present in the uterine lining. But from the 4th week, the placenta takes over.
Origins biological The process of creating placenta would have started about 150 million years ago, when the ancestor of mammals, which still laid eggs, was infected by a virus. The genetic material of this infectious agentis then inserted into the host genome.
Not at all Mariska! the placenta is stuck in the inner part of your uterus and its position is varies from woman to woman and from pregnancy to pregnancy. the baby is in the amniotic sac, wrap with amniotic fluid.
After childbirththe placenta no longer has any reason to exist. Within 30 mins after the birth of the baby, it is expelled by natural and spontaneous contractions: the placenta detaches from the uterus and the maternal vessels rupture. This is called deliverance.
The first four weeks the embryo feeds on the reserves of the egg before the placenta takes over, settling in the top of the uterus. This is where the exchange of nutrients between the mother and the fetus are going to start.
From the 4th month of pregnancy, your baby becomes a real little gourmet. Thanks to the amniotic fluid, you transmit to it the taste of the food you eat. This is why it is essential, during these nine months, to eat of all.
There is no evidence that the consumption of placenta is beneficial to human health or that it can reduce postpartum depression, replenish iron or improve lactation. On the other hand, the potential risks, in particular those of contracting a bacterial infection, are real.
In other regions of China, for example in the city of Jinan (east), placenta reach a higher price: sellers ask for no less than 300 yuan (37 euros) a piece, most of them coming from hospitals according to the official press.
The placenta is usually functional by the end of the third month of pregnancy. It is the organ of exchange between the mother and her fetus, ensuring its respiration and nutrition.
Rather common (15 to 20% of pregnancies are affected), placental abruption is a potentially serious complication. A loss of blood, severe uterine pain and a hardening of the abdomen are symptomatic (in some cases) of this complication, the name of which changes over the course of pregnancy. So we are talking about:
It allows antibodies to pass from the mother to the fetus, which allows it to acquire immune defenses before its own immune system develops; In particular, through the secretion of several factors, the placenta blocks the effects of maternal cytotoxic cells.
Throughout pregnancy, the placenta provides the embryo and then the fetus with the water, nutrients and oxygen it needs. It also evacuates carbon dioxide and metabolic wastes such as urea, excreted by the embryo.
