Many people may have heard of the following statements:
Pregnancy is simply paid for mothers without benefiting
The fetus and mother are parasitic relationship
If there is no placenta, the fetus will absorb all the nutrients of the mother
Nympho
Is this really true?Pregnancy is really a scary thing?I believe that after reading the following article, you will have a clearer understanding of fertility.
01
The mother provides a good growth and development environment for the fetus
When the embryo is in bed in the maternal uterus to form a pregnancy state, as the pregnancy progresses, the formation and development of the fetus, placenta, and amniotic fluid, the mother’s uterus gradually increases, the uterine gorge has also become soft, lengthened to form the lower uterus, and the cervix becomes soft.Cervical mucus increases, which are fully prepared for the growth and delivery of the fetus.
The endometrium during pregnancy is called a molting tissue. According to the position relationship between the embryo and the endometrium of the uterine, it can be divided into three parts: benchmarking, packaging lingement, and authentic molten.The primer is the mother part of the placenta, and the taullat is wrapped in the blastocyst.Millets can protect and nutrition placenta, provide a safe environment for fetal development to ensure normal fetal development.
The placenta is between the fetus and the mother. It is an important organ for material exchange between the two and an important part of the combination of the two.There is also an important bond between the placenta and the fetus is the umbilical cord. There is a umbilical vein in the umbilical cord and two umbilical artery.
Gas exchange, nutritional supply, and fetal metabolites are achieved through umbilical cord and placenta.The blood flowing through the mother’s uterine arteries flows into the placental velvet gap, and the material exchange of the puffy gaps.The metabolic products of the fetus are transported back to the folds, and the mother’s body is discharged through the placenta cycle.
The fetal blood in the placental velvet blood vessels is not directly connected with the mother blood in the velvet gap. Instead, it is across the vascular walls, intervals, and fluffy epithelial cells across the fluffy.Through these substances, the fetus has sufficient nutrition and excrete metabolites to ensure that the fetus can grow well in the mother.
02
The fetus provides a variety of protection for the mother
In the process of breeding the fetus, the fetus will inevitably benefit from the mother.Is it simply paid for the mother and has no benefit?Some people even suspect that the mother and the fetus are parasitic. Is this the case?Parasites refer to two creatures living together. The parasites provide parasites with nutrients and residential places. They benefit one party during the parasitic process and the other party is harmed.There is no parasitic relationship between the mother and the fetus during pregnancy.In the process of breeding of the fetus, some changes in their physical condition will also occur, and many changes in it are also a protection for the mother’s body.The mother stopped ovulation during pregnancy, which played a good protective role in the ovaries.The ovaries can be rest for a period of time during pregnancy, which is conducive to the protection of ovarian function and prevent premature ovarian failure.At the same time, the rest of the ovarian is also great to prevent the occurrence of ovarian tumors.During pregnancy, the endometrium forms a molt under the action of progesterone, and no longer periodic falls off, that is, the cause of menstruation during pregnancy.Under the protection of progesterone during pregnancy, the endometrium can prevent the occurrence of endometrial lesions.At present, many evidence shows that women’s fertility will increase endometrial lesions and even endometrial malignant tumors.In addition, timely and continuous breastfeeding after childbirth can effectively prevent breast disease and even malignant breast tumors.These are the benefits of breeding fetuses to the mother.In addition, did the fetus absorb all the nutrients of the pregnant woman in the process of breeding a new life?of course not.The heart capacity of the mother during pregnancy increases and the blood capacity increases. Under the action of progesterone, the mother’s water sodium is also increased. These are the foundation for the nutritional supply of the fetus, and it also provides reasonable bleeding for the mother’s cycle and during childbirth.Extra -reserves.Generally speaking, the nutrition provided by the mother to the fetus is provided on the basis of ensuring their basic needs (the supply of limited liability). During the pregnancy, the fetus absorbs more nutrients in addition to the amount of reserves, not all the nutrition of the mother.Therefore, the reasonable diet of pregnant women is important to balance nutrition. Excess or too little nutritional supply is not conducive to the health of themselves and the fetus.
Mother and fetal pregnancy should be the relationship between "advancement and accomplishment".Mothers with balanced nutrition and healthy health nourish the growth of the fetus during the birth of the fetus; the breeding process of the fetus also brings many protective effects to the mother’s reproductive system.In this wonderful and magical process, they depend on each other and achieve each other.This is the wonderful magic of life!Author: Zhai Yan’s Chief Physician of the Obstetrics and Gynecology Department of Beijing Chaoyang Hospital affiliated to the Capital Medical University review: The chief physician of the Institute of Science and Technology of the National Health and Health Committee of Zou Yan; deputy director of the Nursing Department of Rao Lin China Welfare Association International Peace and Child Health Hospital
