How is the intrauterine development of the fetus. Pregnancy development of the fetus for weeks, sensations. Sensations of a woman as the fetus develop

Probably, every woman awaiting the appearance of her baby to light, ready under the microscope to look at the transformation of a tiny lump in a cute baby body. But, unfortunately, there is no such possibility.

Although modern medicine already provides a lot of ways to study the development of a child in the womb. Of course, it is pleasant and interesting to learn that your future kid has been hammered by heart or all fingers have been formed.

However, this information is necessary for even before birth, if necessary, begin to influence its physical and mental development.

The main stages of intrauterine development

Many women, already at the pregnancy planning stage, begin to take care of their health strongly. The diet is revised, refuse to harmful habits, adopt folic acid.

Traditionally, the stages of the development of a child in the mother's womb are divided by 3 trimesters, each of which lasts three months or 90 days and is characterized by meaningful changes in the fetal life.

The state of a woman in the early and later pregnancy is also usually unequal. There are oscillations in food behavior and mood.

Consider a Read more Development of a child in the mother's womb on weeks.

First trimester of pregnancy

1 and 2 weeks of pregnancy can be called "conditional", because it is not a birth of a new life, but preparation for it. A hormonal background in the body of a woman changes, the egg cell is prepared for fertilization;
3 weeks is considered a period of conception and falls on the middle of the menstrual cycle. A woman usually does not feel any signs of pregnancy, although pulling pains can appear at the bottom of the abdomen or begin to change food behavior (read on the topic: 3 weeks pregnancy, stomach hurts \u003e\u003e\u003e);
On the 4th week already there is an active development of the embryo. It is still not at all like a future child, but the formation of the head, brain, spine, muscles is already laid. It appears and begins to beat the heart;
By the end of 1 month of intrauterine development in the embryo, the outlines of the handles, legs, ears and eyes are noticeable. He has already managed to grow ten thousand times!

That is why the first trimester is key in the development of the fetus.

At 5-6 weeks of development, the child continues the formation of internal organs (stomach, liver, kidneys, lungs), a circulatory system. Thumbs are distinguishable. Usually a woman begins to notice the first signs of pregnancy, toxicosis may appear (relevant: nausea during pregnancy \u003e\u003e\u003e);
7-8 weeks are characterized by the advent of the vestibular apparatus, as the main body of the child's senses. The baby already has eyelids, jaws. The skeleton develops, joints are formed. The child may react to external stimuli, touch;

At the same time, he begins to move, but the movements are not yet tangible for the future mother, as the baby is still too small. Its weight is 2-4 g, and the length is 12-15 mm. With the help of a special device (stethoscope) you can already hear the heartbeat of the child.

For 9-10 weeks, the child appears on the fingers and nails. Forms are formed. In the brain, the cerebellum develops intensively, designed to respond to coordination of movements. There is a further formation of skeleton bones, skull;

Interesting! After 9 weeks of pregnancy, the embryonic period of intrauterine development ends and fetal begins. From 10 weeks, the embryo becomes a fruit. He has already laid almost all organs. In the following weeks there are their active ripening and development.

On 11-13 weeks there is a significant increase in the head of the child, due to the development of the brain. The first hairs begin to grow. The child can suck the thumb, bending and blending limbs.

He has a kidney, highlighting the urine. The roots of dairy teeth are formed. The kid feels noise, reacts to sounds, warm. He perceives the movements that are transmitted from the mother: if it is inactive, he is calm, if it is active, then the child begins to move.

The first trimester is completed and, from about 14 weeks, it begins a calmer period for a woman, because the threat of miscarriages is significantly reduced.

In addition, usually, if in the early periods of pregnancy, the future mother bothered toxicosis, then in the second trimester he retreats, the woman feels much better.

Second trimester of pregnancy

14-15 weeks;

The formation of the head, handles, legs are completed;
The child weighs about 110 g, and its growth is 12 cm;
His movements become more coordinated;
The kid appears taste sensations, it can react to substances that fall from mom into amniotic fluid;
The amount of urine allocated at the child becomes more.

For 16-17 weeks of intrauterine development, that's what happens:

The skin of the child pink;
He makes grabbing movements, blinks, can open and close the mouth;
The baby grows up to 18 cm and weighs 150 g (weight can fluctuate to 200 g);
It often swallows amniotic fluid;
Head proportions exceed the proportions of the body;
Everyone who has not yet started talking to their child should begin to do this in this period. This contributes to the establishment of better mom's contact with the baby and in the future - the development of speech.

18-19 weeks;

Fetal movements are becoming tangible (read: chapels for 18 weeks of pregnancy, movements \u003e\u003e\u003e);
The child hears the mother's heartbeat and the flow of her blood according to the vessels;
There is an active development of lungs and bronchi;
Begins to work the spleen.

Approximately 20-21 weeks the activity of the child increases markedly:

It moves in the uterus, pushes, moves the limbs, can play with umbilical cord and even smile;
The baby more clearly begins to distinguish between intonation. The more mom will sing to him pleasant songs, the better for the development of his hearing;
In the intestine of the child begins to form the first cal - Mekonia;
The kid grows intensively (length is about 30 cm) and adds in weight (weighs 500-600 g).

On 22-23 weeks, the ratio of head and body becomes more proportional. During this period there is a new round in the development of nervous bonds and brain. The accumulation of adipose tissue occurs. More details you can read in Article 22 of the Pregnancy Week \u003e\u003e\u003e;
24-25 weeks;

The child has a connection of facial expansion with emotions;
He can smile if he is comfortable or angry, if he is dissatisfied and, at the same time, on the face of the corresponding expression: the muscles around the eyes are tense, the lips are compressed. This is confirmed by the photo of the development of the child in the womb;
Some studies suggest that the kid, during this period, is able to see dreams;
Its skin is still very gentle and covered with special lubrication;
The child born on this period is able to survive.

By 26-27 weeks of the intrauterine development, all the bodies of the baby were formed;

His weight ranges from 800 to 1200. Height: 32-35 cm;
With the beginning of the functioning of the endocrine system, the intensive production of own hormones occurs.

If you take into account the development of the child in the mother's womb by months, then this period marks the end of the sixth month of pregnancy.

Third trimester of pregnancy

28-29 weeks;

The child can breathe independently;
It opens his eyes from time to time;
In the uterus, the baby is becoming closer, it begins to take a normal position for childbirth: the head is located below;

During wakefulness, the child's eyes are open, and when sleeping - closes them. With bright light, it is buried;
The skin of the baby is thickened, acquires a bright pink color;
Increase in the amount of digestive organs;

32-33 weeks of intrauterine development;

In this and subsequent period, the growth of the fetus and weight gain becomes very rapid. Its length is 40-45 cm, weight 1500-2000 g.;
There is a formation of immunity;
The skin is smoothed, the fat layer appears under it;
The child is becoming more and more active and everything is more closely in the uterus;
The development of nervous connections continues.

34-35 weeks;

During this period, the kids are strengthened, therefore, quite often, the woman requires an additional calcium reception;
The development of muscle mass continues;
Nails have completely grew;
Cumshots disappear from the skin;
Lightly formed, ready for breathing;
A sucking reflex is actively developing, indicating that the child is preparing for the right food of food required after birth;
Cal, accumulated in the intestine, will be released in the first hours of life born baby;
These weeks for a woman can be marked by the appearance of the first training bouts.

36-37 weeks;

Fully formed genitals, heart. The child is ready for birth;
Merchants are becoming increasingly tangible;
The face of the kid is rounded due to a fat layer;
Cartilage are compacted;
Pregnancy Over 37 weeks is a dundar. In the absence of pathologies and the normal weight of the fetus (approximately 2500-2700 g), the childbirth on this period is most often passing successfully.

38-39 weeks;

Hair growth occurs on the head (they can be up to 2 cm);
The position of the kid in the womb is determined.
The iron is accumulated in its liver, necessary for life after birth;
The development of a whole complex of reflex reactions is completed;
The neck of the uterus begins to open (read the article on this issue: Preparation of the cervix for childbirth \u003e\u003e\u003e).

40-42 weeks are waiting for labor;

All stages of the development of the child in the mother's womb were completed;
By this time, its weight is usually 3000-3500 g or more, growth - from 49 to 55 cm (in rare cases - more);
In some cases, a long-term pregnancy leads to a rejunction of the fetus, then the childbirth can be stimulated to avoid negative consequences for the baby and mom.

It would seem that for almost a year to raise a baby, take care of him and his health, to worry about the pregnancy to go without prejudice to its development. But this period passes so rapidly that most women do not immediately have time to realize that they became young mothers.

And, the more attention was shown to the baby, communicating with him in the process of pregnancy, the stronger the connection of a woman with a child at the time of his appearance on the light and the easier the childbirth should pass.

And the main task of mom during this period is to help the baby feel that life next to her and with other relatives is also safe and even more interesting and diverse than in her tummy.

The ability to dry out and the birth of the fetus is a real miracle that a woman performs. After all, at this time - it is a magic vessel in which the microscopic cell is converted into a full-fledged human body.

The average duration of pregnancy is 280 days, that is, 10 obstetrics (28 days) or 9 calendar months, the countdown is made from the first day to the last menstrual cycle. During this period, a tiny egg in the uterus will have time to develop to the stage of mature fetus - a small little man prepared for outside the morning existence. Are you interested in tracing the development of the baby from month to month? Then take advantage of our calendar Pregnancy.

Stages of pregnancy for months

1 month (1-4 pregnancy Week)
After the fertilization of the egg occurred, the uterine tube launches the cell division process. All processes are made with such rapid at the speed, which is just right to say that "the child grows not by day, but by the hour."

After the expiration of three days after conception, the hump of HCHG begins to produce in the fruit, due to which the female organism is subject to some changes.
During the first three weeks, the fertilized cell becomes embryo.
The kid has a bookmark of all organs.
By the end of the 4th week, blood circulation is launched in the embryo, cord is formed as a connection with the placenta.
The embryo is implanted in the uterus.
The first month of pregnancy ends with the formation of eye wpadin, fastest legs and hands.
By the end of 4 weeks, the appearance of the embryo is comparable to the ear shell and has the magnitude of the sand - about 1 mm.

2 month (5-8 a week)
The fruit ceases to receive food from a fetal egg and immediately after attaching it to the inner walls of the uterus gets food from a woman. From this point on, its development is significantly accelerated.

In the first month, two layers are distinguished in the fruit - endoderma and mesoderma, on the 5th week there is a third - ectoderma, which builds a nervous system, leather, hair, dental enamel. In addition, the embryo marks the formation of a groove that is consistently cooled. It is transformed into the nervous tube - in the future - in chord, central and peripheral system. In the chest is the formation of a primitive heart tube.
At week 6, your baby is exposed to an active organogenesis - the process of forming the most key systems in the body: hands, legs, head.
7 weeks noted by the rapid growth of the head, as the brain is actively developing. In the rounded head you can already distinguish the orders. The formation of the nose and her mouth begins. Two bronchial branches are already present in the field of the future respiratory system. Heart separation on cameras and artery. The appearance of veins also accompanies the conception of such organs as liver, spleen and gallbladder.
At 8 week, ultrasound will demonstrate the picture of the first unconscious movements of the kid. It will be possible to blame the outlines of the handles and fingers, the upper lip, the nose and the oars. For 2 months, the child has a height of 13 mm.

3 month of development (9-12 a week)
For the third month, your baby has to go from the status of the Embryrous in the so-called obstetrician "status" of the fetus.

The 9th week is notable for changes associated with the kid skeleton. Begins the transformation of cartilage in the bone, bending of hands and legs, the final formation of the neck. There will be eyelids, although they are soldered with each other at this stage of development.
10 week - the fetus completes the stage called embryonic development. Fingers are disconnected on the hands and legs. It is still impossible to identify external genitals, but the boy will already begin to develop testosterone.
On 11 there is a complete disappearance of the tail. The child can already be compared with a small man, but his body has not yet adopted those proportions that are peculiar to the newborn. At this stage, 10% of his weight occupies a liver. In the body, kidneys are already working - the urine produced is replenished with spindle water.
12 week - complete completion of organogenesis. The complete formation of all systems and at the subsequent stages of the development of the kid, they simply continue their development.

By the end of 3 months, the fruit reaches 61 mm in growth, and 14 g - in weight.

4 month (13 - 16 weeks)

14 week - the entire system of cartilage, of which the skeleton of the fetus was built, becomes bones. Genitals can already be attributed to a specific floor, but the ultrasound can not yet show them.
15 week - the appearance of the hair cover on the head, the formation of eyebrows. At this stage, the formation of the gallbladder is launched.
16 week - eyes and ears take their final look. Solid elongation of legs - in relation to the body they will become proportional. At this stage, the child is distinguished completely formed nails.

The weight of the child for 4 months equals 130 g, the growth is 12 cm.

5 month (17-20 weeks)

The final formation of grooves on palms and heels, of which the basis for prints in the future.
The size of the kid is equal to the size of the placenta.
18 weeks - the beginning of the perception by the child of external sounds and responding to them.
19 weeks - the slowdown in the rapid growth of the child, from that moment the subcutaneous fat begins to form. Bronchioles are formed in the lungs. The toddler response is noted.
By 20 week, the girl will have a fully formed uterus, but there is still no vagina.

By completion of 5 months, the child will reach 16 cm in growth, and 320 g - in weight.

6 month (21-24 a week)

A bright example of a jump in the development of the nervous system becomes the ability of the kid to swallow the oily fluid.
Dairy and constant teeth in their infancy can be seen on the ultrasound.
Hair growth continues on the head, but their color is still impossible to determine, since it has not yet come to appear the appearance of pigment.
23 Week - On the ultrasound, you can follow the quick movements of the eyes during the dream of a baby, which confirms the high activity of the brain.
24 weeks - the viability of the child at a qualitatively different level begins on this time. In the lungs, the formation of terminal bags at the ends of the capillaries, separated with alveoli using a thin film. Light begin to produce a surfactant - a surface substance that prevents the closure of capillary bags during the respiratory process.

By the end of 6 months, the fruit grows up to 21 cm long, and up to 630 g in weight.

7 month (25 - 28 weeks)

The subcutaneous fat is actively formed, but the child is still thin, has red and wrinkled skin.
The appearance of taste nipples in the language.
There is a normal functioning of all organs, but their development is still continuing.

The origin of the immune system, nevertheless, the child's blood is also replenished with mothers antibodies.
The teeth in the gums are covered with enamel.
Already in the uterine cavity, the child is prepared for an independent existence: it breathes by sprinkling waters (an analogue of the respiratory charge, allowing to increase light), you can observe the sucking cam or finger (the development of the reflex).
The kid is powdered, subcutaneous vessels have already ceased to shift.

By the end of this period of pregnancy, the fruit will reach 40-41 cm in growth, and 1600 g - in weight.

9 month (33 - 36 weeks)

The activity of the child is increasing, its water room is becoming more closely for him.
The ratio of white subcutaneous fat is 8% of its weight.
Light kids are increasingly distinguished by a souffortant.

By 10 months the fruit grows up to 45 cm, and weighs approximately 2500 g.

10 month (37 - 40 weeks)

Lanego - hair loss covering the surface of the head and the calf child.
The original grease is reduced in volume.
The kid takes a position in which it is born (the knees are firmly closed with the chin).
His preparation for independent life is fully completed.

As a rule, full-time children have an increase of 51 cm, and weigh 3400 g.
The final stage of the intrauterine development of the baby behind, and you will have to cope with a serious test - childbirth, after which you will finally get acquainted with your long-awaited treasure.

See how the growth of the fruit looks like from the beginning and to the end.

Even if you are on early, then very soon you will need special underwear for future mothers, and cosmetics from stretch marks and pigmentation on the skin will also be useful.

Pregnancy is a unique physiological process that allows parental cells to connect and form a new organism. The development of the fetus for weeks of pregnancy is the most interesting event that many milfs love to remember. Every day, the week of pregnancy entails the grand changes in the fetus and unforgettable impressions arising from the mother. From this article, future mothers learn a lot of useful and information that interests: when the baby begins to lead an active lifestyle, hear her voice. No less interesting to know about the changes in the weight of the fetus, when the long-awaited ultrasound will take place to recognize the floor of the crumbs.

The intrauterine development of the fetus is divided into two stages:

the embryonic period lasts eight weeks after the fertilization of the egg. At this time, the female is embryo;
the fetal period is counted from the ninth week until childbirth. At this stage of development, a woman is already under his heart.

There is a real duration of childbirth, which is counting from the moment of fertilization and obstetric, originating the first day of the last month. Their difference is 14 days.

Exciting a trip for weeks of pregnancy

First

An important event occurred - fertilization. The zygota starts its formation. Each day and even an hour increases the number of embryo cells by crushing and on the third day it consists of 8 cells, and on fourths from 20. They form a small lump, which moves to the uterus to start full-fledged development and growth.

Second

A fruit egg is attached to the wall of the uterus. Such a process is called implantation, it is a critical moment for the development of the embryo. The mother's body is rebuilt, producing hormones to protect the embryo. Pink or brown discharge can be observed.

At the same week, the cells of the fetal egg cells occurs:

the inner layer is responsible for the formation of lungs, liver, digestive organs;
the middle layer forms the bone and blood circuit;
the outer layer develops the nervous system, skin and hair cover, etc.

Third

This week is preceded by the development of the spinal and brain, the spine is formed.

For 20-21, it is possible to say with confidence that the conception was successful. The embryo consists of a variety of cells, and the tiny heart begins to fight - the fruit is ready for intrauterine changes. The dark discharge appear signals the threat of miscarriage.

Fourth

The embryo reaches the size of the poppy grain - 1, 5 mm. During this period, the basemark of the foundations for internal organs begins, the heartbeat increases, the nervous tube goes into a new phase for the development of the brain, limbs originate. The extraordinary organs are formed: a gusty bag that provides the nutrition of the embryo, Chorion is the future placenta.
