How does a baby develop in the womb?

The expectant mother, expecting the birth of a baby, listens with special interest to the child. Does he really hear, see, understand everything? When does his heart and eyes appear? What is he doing and why is he pushing? To answer all these questions, you need to consider the development of the baby in the womb for weeks.

40 responsible weeks
The birth of a baby is one of the most amazing moments. Such a process takes about 9 months. Obstetricians usually count this period in trimesters, each of which lasts 90 days. But most often the gestational age is expressed in weeks (a total of 40). Moreover, the countdown begins on the first day of the last menstruation.

The health of the future person is laid in the initial weeks of pregnancy. That is why gynecologists insistently recommend preparing for conception. With a planned pregnancy, a woman begins to adhere to the correct lifestyle in advance. Thus, it prevents the appearance of pathologies in the fetus.
I trimester
This is one of the most important periods. A woman should completely stop smoking, taking alcohol and taking drugs (except for drugs recommended by a doctor). Expectant mother needs to walk a lot, eat right and practice moderate physical activity. In order for the fetus to develop correctly, doctors advise a woman to use folic acid. This vitamin protects the embryo from congenital abnormalities.

Already from the 1st week of pregnancy, pregnant women need to take vitamins
So, the development of the child for weeks in the womb occurs as follows.

1st week

This period can be called preparatory. A woman’s egg matures. The patient can learn about the process of ovulation by minor pain in the ovary area. A sperm is suitable for the egg that leaves the ovary. This process can take about 2 days. Then fertilization occurs.

The 1st week of pregnancy is usually the 3rd week since the last menstruation.
2nd week

The zygote (the so-called fertilized egg) moves through the fallopian tube. She heads to the uterus. In the cavity, it attaches to the inner wall. Then begins to share. A similar embryo implant can cause slight bleeding.

The sex of the baby is completely dependent on the sperm fertilizing the egg. Thus, the birth of a daughter or son depends only on the father.
3rd week

The future baby is actively developing. He has a nervous system. Muscle tissue and spine begin to emerge. On the 21st day, the heart appears in the embryo. It immediately begins to pulsate. There is a bookmark of the spinal cord and brain.

4th week

A woman usually learns about pregnancy during this period. There are no periods, periodically there are attacks of dizziness, nausea. A woman becomes irritable, tearful.

Starting from the 4th week, the child is actively developing
How does the baby develop in the womb? In the body of the embryo, blood circulation begins, internal organs such as the kidneys and liver begin to form. The digestive tract is laid.

You can consider parts of the body of the embryo. The head, the beginnings of the limbs are visible. Two bubbles appear on the embryo on either side of the head. From them, eyes will be formed in the future. Auditory passages appear. They will become inner ears.

5th week

The umbilical cord appears. This is the main source of beneficial substances in the body of the embryo. The digestive tract is actively forming. The respiratory system develops. Hands stand out. But while they differ in a paddle-like shape. In the body of the embryo is the nucleation of the sex glands.

6th week

If up to this moment the embryo was a little like a human being, now the face is beginning to “emerge”. His eyes appear, jaws form, his nose becomes distinguishable. A colored pigment is produced in the eyes, and the retina appears. Limbs develop. They bend at the knees and elbows. The hands are clenched into tiny fists. Fingers begin to appear.

The embryo already has a gut. The latter is quite large, so it does not fit in the stomach and is partially located in the umbilical cord. The development of the reproductive system continues. But it is not yet possible to determine the gender of the unborn child.

7th week

To understand what a baby looks like in the womb at week 7, you need to take a ruler. The embryo’s body is only 2.3 cm long and weighs about 2 g. The baby’s tail disappears, serving as the end of the spine. The placenta begins to develop. She will take on many functions.

The fetal heart becomes four-chamber, large vessels appear. Endocrine glands are born. The embryo already has fingers. The baby has a tip of the nose, eyelids develop. The organs of the reproductive system are formed (ovaries in girls or testicles in boys).

8th week

Reproductive organs are actively formed. However, it is still difficult to reliably determine the sex of the infant. The kidneys are already capable of producing urine. The embryo moves vigorously in the womb.
