34 to 35 days of gestation, the role of the placenta

Although preparations for the construction of the placenta began two months ago, it is only today that the placenta begins to form. The placenta plays a very important role for the fetal baby.

Respiratory function

The placenta sends oxygen to the fetus through the blood in the mother's body, and then sends the carbon dioxide in the fetal baby's blood back to the mother for discharge, which is responsible for the function of the fetal baby's respiratory organs.

Transport of nutrients

The placenta is like a complex "transport machine", which can transport the sugars, amino acids and trace elements needed for the growth and development of the fetal baby. The placenta can also transport the disease-resistant substances (immune substances) in the mother's body to the fetal baby through the placenta, and its strong immunity can be exerted until 6 months after the birth of the fetal baby.

Excretory function

Metabolic waste products from fetal babies, such as urea in the urine and bilirubin, which cause jaundice in newborns, are excreted through the placenta through the mother. Therefore, from this point of view, the placenta also has a excretory function, similar to the function of the kidneys.

The placenta is the warehouse that provides nutrition, and the umbilical cord is a transportation line.

Resisting the viral placenta has the function of resisting the invasion of harmful substances such as bacteria and viruses into the fetal baby. However, more than a dozen viruses such as rubella virus, cytomegalovirus, and influenza virus can still invade the fetal baby through the placenta.

Adjust hormones

The placenta secretes corresponding hormones at different stages to ensure the development of the fetus. For example, in the first trimester, the secretion of chorionic gonadotropin is the mainstay, and the secretion of progesterone and estrogen is also secreted, and at the time of pregnancy, it secretes hormones that promote contractions and the delivery of the fetus.
