The role of the placenta in the development of the fetus
The placenta is a temporary organ that develops in the female body during pregnancy. It serves as a kind of connecting bridge between the body of the mother and her future baby. The placenta supplies the fetus with nutrients and oxygen, removes toxins and waste of its vital activity, filters the blood of a pregnant woman, protecting her child from infections and other threats. After all, the immunity of the baby in the womb of the mother is too weak and not developed in order to defend itself.
Given the importance of the placenta in the normal development of the fetus, doctors closely monitor its condition during the bearing of the baby. The placenta is fully formed by the 4th month of pregnancy. Before this period, its functions are distributed between the fetal membrane and the yellow body.
For the development of the baby in the womb, the correct location of the placenta is important, which affects the course of the pregnancy as a whole.
How should the placenta be located?
What are the features of the location and influence of the placenta on pregnancy?
The ideal option is to attach the placenta to the back of the uterus in its upper part, near the bottom. The walls of the uterus are arranged so that with the growth and development of the fetus they are greatly stretched. But this stretching is not uniform. The peculiarity of the uterus is that the stretching occurs more along the front wall. This wall becomes thinner and stretches more. And the rear wall remains quite dense. It is less subjected to stretching. For this reason, nature laid down the attachment of the fetus to the posterior wall, because the placenta does not possess the property of stretching. That is, the placenta on the back wall experiences less stress.
Thus, the attachment of the placenta to the posterior wall is an ideal variant of the attachment of the fetus and the development of the placenta itself.
Variations of the location of the placenta ??h2>
For various reasons, the fetus can be attached not only to the posterior wall of the uterus. Quite often there is also a lateral fastening. This can be fastening to the right or left of the back wall. Sometimes the placenta is attached to the anterior wall of the uterus. Such variants of its location pathology are not considered. This deviation from the ideal location.
Women who have a lateral placental arrangement, very often without complications and problems, bear children and give birth to them naturally.
Yes, the placenta on the front wall is subjected to high loads due to stretching the walls of the uterus and fetal movements. This in a certain way increases the risk of its damage, as well as the risk of premature detachment of the placenta. Perhaps also because of the stretching of the muscles of the uterus, the placenta is lowered to the uterus of the uterus. The worst variant of such lowering is the overlap of the exit from the uterus in the birth canal. When between the edge of the placenta and the throat of the cervix will remain 6 centimeters or less, the doctors say about low placentation. If the placenta completely or partially blocks the exit from the uterus, then this pathology is called placenta previa.
Symptoms of anterior presentation and threat
The causes of placenta previa on the anterior wall are not fully understood. One of them is damage to the endometrium (inner layer of the uterus).
Often the anterior placenta previa is asymptomatic. The main thing at the same time in time to diagnose the presentation. Sometimes such a presentation of the placenta is accompanied by bleeding. It indicates that a premature detachment of the placenta has occurred. This is the main threat of this presentation. If the placenta is low or blocks the exit from the uterus, then the child presses on her with a mass of his body. The fruit clamps the blood vessels of the placenta, which is fraught with its oxygen starvation.
Bleeding at the front presentation can begin in the second trimester, after the formation of the placenta. But in most cases if bleeding happens, then in the third trimester or before the very birth. If a woman notices vaginal bleeding, then you need to see a doctor immediately.
When the placenta completely blocks the exit from the uterus, the birth is naturally eliminated. If the presentation is partial, then such births are possible.
From all of the above, that the presentation on the front wall is not a verdict. A woman under the able guidance of her doctor should remain calm and confident that with the baby everything will be in order. And for this it is necessary to follow from the very beginning of pregnancy all the medical recommendations and prescriptions.
