Stages of fetal development
The embryo consists of several stages in the womb of the pregnant mother. The journey of fetal development begins since the egg meets sperm. Fertilization is fertilized within one week of fertilization. The fertilized egg or so-called capsule is found in the uterus. In groups and become the mass of the internal aggregated cells of the embryo while the amniotic sac is formed from external cells and placenta, and the capsule capsules dissolve their protective membrane in a process called hatching, then disappear into the uterine wall.
- In the fifth week, the embryo is the size of the sesame seed and the internal cells start again in order to give the embryo shape and form its primary organs. The brain of the embryo and the spinal cord can be seen through its semi-transparent skin. In this period the circulatory system is fully formed and its heart begins to throb and withdraw food and oxygen Via the umbilical cord and the newly formed placenta.
- In the ninth week the embryonic tendency disappears and the fetus becomes closer to the human body day after day through the growth of limbs, fingers, nose, eyes, and small ear lids. The child takes the size of the grape and weighs a portion of the ounce.
- From 10th to 14th week:
- In the tenth week is barely the size of orange, and enter the embryo stage of growth and determine the features of the face and consists of buds under the gums in the next stage will grow tissues and organs quickly.
- In the twelfth week, the kidneys begin to produce urine, which will soon begin to fetch the embryo into amniotic fluid.
- In the fourteenth week, the eyes of the embryo and its ears move to its place where the fetus can tilt its eyes and polarize and play and fertilize and thus the mother has entered the second stage of pregnancy.
- 15 weeks to the twentieth week: At this stage the size of the fetus grows to twice as his body grows, and his nervous system quickly ripens, and the skeleton also changes and starts the cartilage of soft and hard to move to the bones and starts this first in the arms and legs, and develops his hearing at high speed and allocates the brain Certain areas of touch, taste, hearing, consideration, and smell. At this stage, the fetus can hear the mother’s pulse and hear her voice.

- At this stage, the fetus’s sense of touch develops, and then the fetus responds to the mother’s touch on her stomach with strong movements and kicking, and can touch his face and anything around him, including the umbilical cord.
- In the twenty-third week the fetus will be able to swallow as the lungs form millions of small branches of the so-called people to start the fetus after breathing through the airways.
- In the twenty-fourth week a fetus can live out of the womb with a lot of medical attention.
- The twenty-seventh week The embryo opens its eyelids in response to the involuntary but it does not spring, and its lips are composed and have small tattoos on his tongue, now weighs two pounds and a four-tenth of an inch, so the mother has only one stage of pregnancy.
- From the 28th week to the 37th week:
- At this stage, the fetus increases threefold to the birth, leaving layers of fat to help keep the uterus warm. The skeleton, with the exception of the bones of its head, is not yet welded, allowing its bones to expand. At this stage, millions of neurons are formed. It can now open its eyes and see the light. Leaking through the uterus, and he can hear well.
- In the 37th week, the fetus’s skin is pink and soft, gaining about an ounce a day, weighs approximately six pounds, and is considered to have fully completed the gestation period.
- At birth most children turn their heads down, and the child remains in this position and his head is stable in the pelvic area in preparation for going out into the world.
