Is the placenta on the right side?

Because everyone's physique and habits are different, the position of the placenta is also different. Some people say that if the placenta is on the right, it means it is a girl. In fact, this has no scientific basis. The placenta plays a very important role during pregnancy. It can provide the baby with the necessary nutrients and help the baby shield from other viruses. The most important thing is that it can prevent the pregnant mother's body from rejecting the baby.

Function

1. Material exchange function

Gas exchange includes oxygen exchange and carbon dioxide exchange; nutrient supply includes all nutrients needed for fetal development; and elimination of metabolic products in the fetus.

2. Defense function

Although the barrier function of the placenta is extremely limited, it does have a certain barrier function against some bacteria, pathogens and drugs.

3. Synthesis function

Such as human chorionic gonadotropin, human placental lactogen, estrogen, progesterone, uterine tocinase, thermostable alkaline phosphatase, cytokines and growth factors.

4. Immune function

The specific mechanism by which the mother can accept and not reject the fetus is still unclear.

5. Other functions

(1) Storage function. For example, in the early stages of pregnancy, the placenta grows very quickly. A large amount of nutrients (protein, glycogen, calcium, iron, etc.) are stored in the placental cells to meet the needs of fetal growth.

(2) Metabolic regulation function. The placenta has a function equivalent to that of the liver. It not only stores nutrients but also has a regulatory effect. In the later stages of development, the fetal liver gradually grows and develops fully, and the metabolic regulatory function of the placenta gradually decreases and even disappears. The placenta can also transform and synthesize some substances, perform multiple functions of the digestive tract, lungs, kidneys, liver and endocrine glands, and regulate these functions to protect the fetus and mother so that the pregnancy proceeds smoothly.
