Pregnancy or gestation is the status of the woman who carries the fruit of conception.
From pregnancy begins with fertilization with sperm that normally occurs in the outer third of the fallopian tube. Semen begins its changes already in the uterus and its functional maturation called capacitating acquires the ability to pierce the wall of the egg and then insert the paternal DNA in its cytoplasm. Subsequently, the zygote thus formed, continues its path along the pipe to reach the uterus and in the meantime bring the melting process of keeping the parents (23 chromosomes of maternal and paternal chromosomes 23). This phase lasts about 24 hours, and only then starts the segmentation of the fertilized egg into two cells, then 4 and so on until you reach 64, and in the meantime, this cluster of lodge’s uterine endometrial cells, which at this stage of cycle is ready to accept it.
Then the germ of pregnancy begins with fertilization and ends two weeks later, with the segmentation of the zygote and formation of cysts burst.
In the first 4 weeks of pregnancy, the union of sperm and egg comes a new life. In this zero nucleuses fertilized only 0.12 mm. Yet in its genetic map has already decided if it will be a child or a child if the mother has brown eyes or curly or straight hair.
After four hours the embryo in a woman's body begins to divide into two identical cells. From this point the division continues and the cells divide continuously.
The memory device almost spherical takes five days to descend from the tube to the uterus, and then begins to hide in the endometrial. At this moment the size of a pinhead. A few days later, a pregnancy test is already able to detect the status of 'pending' sweet.
Medicine calculates time differently reality: it is said those just four weeks even if fertilization occurred 14 days earlier. Part of the calculation, in fact, the first day of the last menstruation.
5-8 weeks of pregnancy the baby's blood vessels are connected to the mother's bloodstream. floor plan for the future mother becomes possible to recognize that inside she is growing a new life. In the fifth week of fetal heart begins to beat and hands and feet sprout like small buds. A few days after the child are already able to move his head.
To move the child's development is important. sensory experiences that accumulate to affect his brain development. At the end of the month the child is about two inches long and weighs about 10 grams.
The tenth week of pregnancy, the child is capable of sensory stimuli on his skin. The liver begins to produce liquid bile. Towards the end of the third month the child had drunk amniotic fluid and expels him. These movements allow swallowing to coach the lungs and kidneys.
Even the cerebral cortex begins to grow. Later it became part of the brain where, according to scientists, is the personality of an individual.
The child participates in the life of the mother and is able to feel the excitement, happiness and stress. If the mother is afraid, the adrenaline is secreted in his body, causing increased heart rate.
At the end of the third month the baby is about seven inches and weighs about 250 grams.
The pregnancy continued and we arrived to the period between 13 and 16 weeks, now, movements of belly began to be turbulent. The streets of nerve conduction in the child's body were linked together to enable him to turn around, swing and even turn somersaults.
The fetus still has much space available, and during its movement affects only slightly the uterine wall. Although the mothers already feel delicate movements around week 15. Gradually, even the eyeballs begin to move, even if the eyelids are still sealed.
At the end of the fourth month the child is about 16 cm and weighs about 250 grams.
We arrived between 17 and 20 weeks of pregnancy, the baby is now able to grow and train intensely to life outside the womb. For example, exercise its meaning: the first is to develop flavor. In the 20th week of pregnancy, your baby has a number of taste buds ten times higher at birth and loves everything that is sweet.
Even the ears are able to perceive sounds. At first, however, the fetus hears only the sounds produced by the mother: her heartbeat, digestion, and the noise associated with the maternal voice.
At the end of the fourth month the child is about 25 cm and weighs about 400 grams.
21-24 weeks is a little 'luck with the ultrasound around 20 weeks you can see the baby sucking her thumb. Or maybe you'll see him playing with the umbilical cord. Now your body is concerned, it passes hands and touches the face arms and legs, his movements become faster.
You may feel pain, sometimes the amniotic fluid and pass through the hiccups - that his mother will feel a slight tap against his belly.
At the end of the fifth month the baby is about 30 cm and weighs between 600 and 700 grams.
Communication with our child starts between 25 and 28 weeks of pregnancy, the child gradually begins to turn its attention to the outside world. Now you can hear what is happening outside: traffic noise, the voices of other people, music. Develop preferences - such as classical music.
Now the streets of nerve conduction eyes already connected to the cerebral cortex. Around week 26, the small door for the first times the eyelids. Even if it reaches only 1% of daylight, the child is sensitive to light. If your stomach is a strong bet beam of light like a flashlight, the child looks with curiosity in this direction.
Finally, learn the meaning of pleasure. Doctors have observed that ultrasound, when a guy sucks his thumb, the pleasure it produces creates a hardening of its members.
At the end of the seventh month the child measure 35-37 cm and weighs between 1000 and 1200 grams.
Finally we got between 29 and 32 weeks of pregnancy, a thought that makes me feel comfortable, if the child born today would already be able to survive with the help of medical support. premature birth, however, rather problematic lung maturation should be supported with medication; the child is exposed to infection and must be fed artificially.
Children become more alert and react to external contacts. Warns when her mother, who kindly hand on his stomach or if your partner gently press the belly with a finger. Perhaps the child "encounters helped transform or approaching the point where his hand is at rest.
At the end of the eighth month the child size 40 to 42 cm and weighs between 1,700 and 2,000 grams.
It 'started the countdown to the birth is between 33 and 36 weeks of pregnancy and the baby prepares for life "true". Now, in the belly is a bit 'tight and can barely turn around.
Swallows every day up to 3 liters of amniotic fluid to practice in this way the stomach, intestines and bladder. It often sucks his thumb and kicking strongly, so that the skin is massaged from the uterine wall, often opens his eyes.
At the end of the ninth month the baby is about 46 cm and weighs between 2500 and 3000 grams.
Finally we reached the desired week of pregnancy between 36 and 40, all bodies are ready to work and were also laid the foundations of brain components: over 100 million brain cells waiting to be properly "fed". This is largely thanks to the experiences that the child will do after birth. The memory still works already in the womb: scientists have discovered that the fetus in the 37th week of pregnancy is able to remember a sequence of sounds for at least 24 hours.
After 40 weeks the child leaves the nest.
