Pregnancy is one of the periods that most couples experience during this period. This course has its own conditions and people must take the necessary care in all respects. Because any wrongdoing will cause harm to the fetus. The fetus feeds directly on the nutrients in the mother’s body and also receives the oxygen it needs.
In the placenta, the mother and fetus’s blood are placed together but not mixed together. The umbilical cord blood vessels in the placenta form clusters of structures. . Crosses, encloses them.
Due to the importance of the placenta in meeting the needs of the fetus, we talked to one of the specialists. Dr. Mina Movahedi, gynecological surgeon and director of the obstetrics and gynecology surgery department of Tehran Judiciary Hospital, says: Is established. The mother’s blood enters the placental cells directly and makes them alcoholic.
In fact, mother-fetus communication is through placental villi cells. The fetal blood passes through the space between these villi and does not communicate directly with the mother’s blood. This is important when it comes to the baby’s immunology and disease transmission. 12 days after pregnancy, the cavity formed in the human placenta is detectable, and from the 17th day, blood flow is established in the placenta.
If the placenta’s drinking vessels do not form, pregnancy is abnormal, in which case the placental cells connect and form blisters. In these conditions, the placenta is sick, which in the past was called this childish condition.
If the mother is not well nourished or contracted a viral or bacterial disease, the placenta becomes ill and fetal growth is delayed; It may even lead to fetal death. For this reason, in addition to the condition of the mother and fetus, specialists in the examination of pregnant mothers thoroughly examine the condition of the placenta so that the health of the mother and fetus is not endangered in the event of a problem.
She continues: The weight of the placenta, along with the umbilical cord and the placenta’s membranes and building blocks, reaches 500 grams at the end of pregnancy and its diameter reaches 15-20 cm. Doctors check the placenta to find out if the baby is healthy after birth and report any abnormalities, large or small, as this helps to diagnose the baby’s illness early.
“The placenta acts as a barrier that many foods, drugs, viruses and bacteria cannot cross,” he said, noting that some drugs cross the placenta. For this reason, doctors try to prescribe drugs during pregnancy that do not harm the mother or fetus.
The umbilical cord consists of two blood vessels, one that carries oxygen-free blood to the placenta and the other, which is the umbilical vein of the placenta, which carries oxygenated blood to the fetus. So that the fetus has no problem receiving oxygen.
Abnormally, the placenta may be very small or large. Placental inflammation (thrombosis) may be caused by microbial or viral diseases. In some cases, due to bacterial diseases or insufficient blood and nutrients to the mother, the placenta remains small and there are problems in the process of oxygenation to the fetus.
In thromboplastic disease, the placenta enlarges and grows into a vesicle (blister) and there is virtually no embryo; In this case, the pregnancy period should end.
Placental tumors, which are mostly vascular tumors (hemangiomas), although less common, but cause fetal problems. These tumors are associated with low fetal weight. This is very important. The mother should see a doctor if she sees severe pain, especially in the last months of pregnancy, or bloody discharge, or a feeling of reduced fetal movement.
In this case, she may have a ruptured placenta, which is the most urgent problem for the pregnant mother and her fetus. In this situation, he should be taken care of by a doctor immediately
Especially when the placenta is located in the anterior part of the uterus and the mother’s abdomen is traumatized; Because in these conditions, there is a possibility of placental bleeding. The treating doctor finds the problem with ultrasound and examination, and in some cases, the mother is treated and there is no problem for the fetus. In some cases, the pregnancy must be terminated;
If this happens in the last months of pregnancy, the baby will survive. The obstetrician adds: In the early months of pregnancy, the mother should see a doctor if she sees a bloody discharge; The placenta may be down and the mother needs special care.
In this case, with a sonography, the doctor notices the problems and takes the necessary measures. Such a mother needs to rest and in some cases, medication is prescribed. During this period, you should pay attention to your natural nutrition. It is better for mothers to see a doctor and counselor before pregnancy, and if they have certain diseases, they should discuss it with a specialist.
