How conception occurs, people learn even in schools thanks to the anatomy course. But not many people know what happens next. How does the baby eat in the womb?

The beginning of a new life

The first days after fertilization, the egg takes nutrients from its own yolk sac. This happens until it is implanted into the wall of the uterus and gets a placenta. While the fetus is in the mother's stomach, it receives all the necessary substances from her body. Based on this, a pregnant woman should diversify her diet and eat well.

She must definitely use all the necessary vitamins, minerals, limit the use of smoked, salty, spicy. This is very important for the development of the baby.

There is an opinion among the people that a newly born baby is like a "white" sheet of paper. But this is far from the case. What does a child feel in the womb? He also feels all the emotions that his mother experiences, whether it is joy or anxiety, emotions or happiness. It is affected by both diseases and the situation in the family.

After 4 weeks, the embryo receives the necessary nutrients and oxygen through the chorionic villi, which turns into the placenta. It not only protects the baby from internal and external factors, but also through it the mother and the fetus exchange the substances necessary for obtaining energy. A real abode! The products of the baby's metabolism are also excreted through the placenta. It is also commonly called a "children's place".

It is very interesting how the fetus eats in the womb. Let's say the future mother ate an apple. The digestive system breaks down nutrients into simple molecules. After that, the process of their absorption into the blood begins, which delivers all the necessary components to the embryo's body.

How does the baby eat in the womb?

Through the umbilical cord attached to the placenta, the fetus is directly fed. There are 2 arteries and 1 vein in it. Venous blood flows through the arteries, and arterial blood flows through the vein. Venous blood flows from the baby towards the placenta and stores metabolic products. That's how simple it is! Now you know how the baby eats in the womb. Interestingly, the width and length of the umbilical cord grows with the child. By the time it is born, its dimensions can reach from 30 centimeters to a whole meter.

Some nuances

How the baby is fed in the womb, we have already considered. But it should be noted that the baby eats the same as the mother only if she uses all the necessary vitamins and elements. And if the mother's nutrition is defective, the baby takes all the necessary "building materials" for the growing body from her tissues and cells. Is it dangerous for a woman? Of course yes! Therefore, the state of her health is deteriorating. There are problems with hair, teeth, nails. The child's need for calcium is great, since he must create his own skeleton out of "nothing".

If the mother uses harmful substances

How does a child eat in the womb, if she does not think about the consequences at all. Do not forget that the child will get not only useful, but also harmful substances to the small body, if the mother smokes, uses alcohol or drugs. This will adversely affect the health of the future baby. Doctors advise you to give up these harmful habits in advance before planning a pregnancy.

Oxygen for baby

How does the fetus breathe and feed in the womb? It is very important for any living being, including a person, to get oxygen, it is impossible to live without it. If the brain is supplied with insufficient oxygen, then it suffers. The embryo does not breathe with the help of the lungs, it receives the right amount of oxygen through the placenta. Therefore, it is so important that mom breathes properly and stays in the fresh air as long as possible. And during childbirth, proper breathing is important. It will help to keep the child in excellent condition.
