The fetus needs to live in the mother's womb for ten months, but most people do not know where the fetus lives in the mother's womb. There are two theories: the first is that the fetus is in the mother's uterus, and the second is that the fetus is in the placenta. So is the fetus in the placenta?
The baby is not in the placenta, the fetus is wrapped in amniotic fluid, which in turn is wrapped in amniotic membrane. The uterus is located on the outermost layer of the amniotic membrane, protecting it, so the fetus receives many layers of protection. However, the entire development process of the fetus cannot be separated from the placenta, which is the main place for the mother's body and the fetus to transmit nutrients. So the nutrition of the placenta and fetus is closely related. During fetal growth, some useless substances are metabolized and eliminated from the body through the placenta.
The nutrients absorbed by pregnant mothers are all passed from the placenta to the fetus, and the oxygen in the mother's body can be transmitted to the fetus through the placenta, so the fetus can survive without eating or breathing. Many metabolic products produced by the fetus during its growth and development are aggregated in the placenta and then excreted through the mother's body. As the fetus grows, various hormones are constantly synthesized in the placenta, which are beneficial for the baby's development and growth. So although the baby is not in the placenta, it still has many effects on the baby.
