Fetus


In biology, the conceived but not born child is called a fetus, which is no longer an embryo. For animals and for human beings, the fetus represents the product of fertilization, which has already passed the embryonic stage and continues its development process. The fetus evolves inside a kind of bag that is inside the mother’s body.
By ceasing to be an embryo, the fetus has the ability to withstand the damage that can be caused by drugs, alcohol, some medications, nutritional deficiencies or infections from the mother, among other things.
In humans, from the ninth month of gestation (and until the time of birth) the embryo is already considered a fetus. Now her face can be seen more clearly, as well as her genitals, which means that by this stage, the mother already knows if she is going to have a girl or a boy.

The fetus has a very different circulatory system from that of humans who have already been born, especially since its lungs do not yet work; This means that the oxygen that the fetus receives comes from the mother through the umbilical cord and the placenta.

On the other hand, in animals such as dogs for example, the embryo becomes a fetus at 30 days of gestation, at this stage the animal’s organs are already formed.

Returning again to the case of human beings, we must also highlight the importance of taking care of food and also the consumption of vitamins such as folic acid and iron, so that the fetus can begin to develop perfectly. The lack of them leads to the appearance of anomalies or congenital malformations that would end up causing the fetus some type of permanent disability at birth. From there also arises the importance of prenatal check-ups, since through them all these things can be prevented, in addition to applying the necessary corrective measures in case any abnormality occurs.

Currently, there are equipment such as ultrasound, which allow monitoring the evolution of the fetus, as well as being able to determine the precise time of pregnancy. Through ultrasound, the doctor will be able to know the length of the femur, the circumference of the skull, the fetal weight and the length of the head to the coccyx.
