What process does a child need to go through to be born? Do you feel the power of life?

The most amazing thing in the world is life. Biologically speaking, life originates from the union of sperm and egg. After the sperm and egg combine, they form what we know as a "fertilized egg". Then How does a fertilized egg evolve into a fetus?

Many people want to take a look at this process. Today I will take you to understand this mysterious process!

In fact, the evolution of fertilized eggs is not a strange secret, because decades ago, in an era when technology was not yet developed, an American photographer recorded this process .

It was he who spent more than ten years diligently and became one of the important factors in promoting the study of the evolution history of sperm and eggs. How do sperm eggs "evolve" into babies under the lens? Step 1: Sperm and egg pairing

When a couple has sex, the male’s sperm will slowly swim into the uterus through the female’s fallopian tube. At this time, the number of sperm reaches hundreds of millions. Although it swims in the fallopian tube, There are many sperm inside, but only one of them can pair with the egg.

Of course, it is relatively rare for multiple births to occur because more than two sperm have received the "yes" from the egg. Step 2: Form a fertilized egg

After the sperm and egg are successfully paired, a fertilized egg will gradually form, which can also be called an "embryo" in medicine. The embryo at this time cannot actually be called a formal "living body", because the embryo needs about 8 to 10 days. Only when the embryo successfully implants on the uterine wall and survives can it be regarded as the "origin of life." ". Step 3: Development stage

The earliest part of the human body that begins to develop is the brain. The embryo also "evolves" from the brain first. When the embryo evolves the brain, it is like a pistachio that has been opened. A small touch of green exposed like a pistachio is the developing head of the fetus.

I have to say that life is really magical. It is unimaginable that such weird shapes will grow into our babies in the future.

When the embryo develops for about 3 weeks, the fetal heart also begins to evolve. This stage is the most important, because this stage is the key to judging whether the embryo can survive healthily. If the small heart develops If it is good, it can ensure a strong source of life for the fetus to continue to live vigorously.

About one month into pregnancy, the fetus’s spine and limbs also begin to grow. At this time, due to the action of amniotic fluid, the development speed of the limbs is relatively rapid.

The face of the fetus is slowly taking shape, but the facial features are still not clearly identifiable and are a bit "strange", making it difficult to connect them with our current faces.

About 6 to 7 weeks of pregnancy, the little human shape takes shape, probably like a curled up baby. The limbs have grown, but the toes and fingers are still stuck together. At this time, The eyes, mouth, and nose of the fetus can also be found in the blur. Thinking that soon we will be able to see an appearance that is close to what we know about the fetus, I can't help but feel a little happy!

At about 8 weeks of pregnancy, the fetus can already see a clearer appearance. Whether it is the limbs or the face, it can be clearly observed.

Around 10 weeks of pregnancy, the baby’s fingers and toes are also separated, and the skin becomes slightly thicker. If you observe carefully, you will also find that the fetal eyes are not yet fully developed, especially the eyelids. It cannot be completely closed.

At about 16 weeks of pregnancy, the fetus is already trying to do various actions, such as touching its body curiously and moving its little hands and feet.

Using relatively high-power color ultrasound, you can also observe the blood vessel distribution on the skin of the fetus. The structure of the human body is indeed amazing!

After 18 weeks of pregnancy, the average fetus can grow to about 14 centimeters. At this stage, their fingernails can be observed, and their facial features show a clearer appearance for the first time, but they still look "ugly". Fetuses at 20 weeks of pregnancy will grow fetal hair, and their bodies will become more flexible. At this time, it is not a problem to do a 360° flip. From this stage, pregnant mothers will be able to feel strong or gentle fetal movements. .

At 36 weeks of pregnancy, the fetus has basically entered the mature stage. Except for the organs, all parts of the body have generally been finalized. However, the organs will gradually become stronger and in the process of gradual "evolution" , the baby's head also begins to face downwards, and it will be ready to enter the basin after about 40 weeks. After that, the baby will usher in a new life.

After understanding this, do pregnant mothers have a better understanding of the growth process of the fetus? Life is really amazing, it can actually grow into a baby from the union of two reproductive cells!

Of course, it is not just the fetuses that are more magical and tenacious, but also the pregnant mothers, who have to endure all kinds of discomfort and pain during pregnancy to bring their babies safely into the world.

Some people say that God created mothers to bring us love. Just calling the word mother can move people's hearts
