Composition and Placenta in Human Development and Structure of placenta in human
In the ninth day of embryonic growth, the Blastocyte sac is inserted into the endometrium, where the thrombocytopenia is specialized in the embryonic disk area to form an outer layer called the cell-syncytiotrophoblast or syncytium, and an inner layer called Cytotrophoblast . At the same time, the basic tissue of the lining of the uterus becomes the Edematous. The cells of this cell become more and more permeable to the lining of the uterus, so the cells of this layer become attached to the cells lining the blood vessels of the mother and enter the mother's blood into the lacunae holes in the cell-built layer. The choroid uterine circulation begins between the mother and her baby. The cells are then concentrated next to the embryonic growth zone, consisting of cellular poles surrounded by cellular helix. These structures are called primary stem villi and when mesenchymal cells enter these structures, the chorionic plate is called secondary stem villi. During these events, there are significant structural changes to the uterus. The fall zone is characterized by three areas:
1. Decidua Capsularis is the area covered by the sachet.
2. Decidua basalis is the area below the mucosa that is later the uterine part of the placenta.
3. Decidua parietalis is the remaining lining of the uterus.
The occipital fallopia is applied to the parietal wall at the third month of pregnancy, leading to the disappearance of the villus from this area. The placenta part of the placenta is then called the placenta.
The part of the placenta under the base fall is called the Chorion frondosum velvet placenta. Both the basal placenta and the placenta are the so-called placenta placenta. The choroidal villi during the fourth month of pregnancy is surrounded by a reduced layer of cellular-built and a few cells of the cellular epithelium.
The size of the vesicles increases and branches in the advanced stages of pregnancy. Their clusters are called Cotyledons, which are separated by placental septa.
At the end of the pregnancy, the placenta becomes a disc with a diameter of 15-125cm and a thickness of 3cm (Chamberlain, 1996; Langman, 1995).
