Five "strange" things are done by each fetus in his mother's womb

People remember nothing about what they did when they were in the womb of their mothers, but medical researchers have uncovered several things a fetus does before coming to life.
According to ScienceFocus, the embryo at the beginning of formation, a change in the blood vessels within the uterus for the creation of placenta, which is a vital process during pregnancy.

Thanks to this placenta, the body of the pregnant woman transfers food and oxygen to the fetus within the uterus. Moreover, the waste is carried out, but the interaction between the mother and the child does not stop there.

Studies reveal that a number of fetal cells are transmitted to the mother. Blood analyzes reveal that these cells remain present even after decades of pregnancy and childbirth. In other cases, stem cells move from the fetus to the mother's heart and have a positive role in improving the pulse.

 One of the things we may not know is that the embryo is at the beginning of its shape similar to the thickness of the shrimp as it looks as if it has a tail, but this disappears with the passage of time in the womb, leaving only a small bone that we feel sometimes when sitting.

Researchers say this is common to humans and animals such as orchids, elephants and chickens, and it is mainly related to developments in the evolution and change of organisms over millions of years.

In third, fetal fingers take their natural shape after being in the form of paddles, through a process known as "cell suicide". This shift occurs during the eighth week of pregnancy.

The fourth may seem deplorable, but the fetus drinks his urine. After ten weeks of pregnancy, he begins to drink liquid in the uterus and then returns to his urine at a later stage.

Contrary to what we might think, the fetus produces a large number of neurons during the first pregnancy, and when it ensures the connection between these nerves and several areas of the body, some cells die that realize they are no longer useful.
