This is how the fetus develops


The pregnancy is divided into three quarters and three trimesters. What happens in a trimester? Read about how your baby develops, how the embryo fetus will be! A brief overview of a long journey with the help of health.howstuffworks.com. There are puppies who are almost whole first trimester "lags", since the first few weeks of pregnancy are unnoticeable. In the first few weeks after conception, the only egg cell division to date is. A lean cell develops a placenta, the rest become an embryo. Imagine the latter as a four-layer disk in which each layer represents important things. The outer layer, the ectoderm, takes care of the skin, hair, gums and the nervous system. The inner layer, the endoderma of the intestines and the lungs develop. Medium layers are responsible for the growth of the heart, bones, and muscles. The 3-week embryo is less than 0.5 cm in size and has an oval shape. In the next few weeks, he will begin to develop an ubiquitous ubiquitous form, with an increasingly elaborate shape, an embryo head and a tail. The spinal cord, brain, heart, small eyes, arms and legs begin to take shape. At week 4, his face begins to form, his ears, nose, and mouth open. By the time she is 8 weeks old, her head is incredibly large with respect to her body, and by that time the embryo is about 3.5 cm, which from that week on is known as a fetus. His toes and toes appear, his tiny little heart beating. 5 weeks embryo By the time you reach the end of your first trimester, the fetal genitals will develop, the teeth appear in the mouth, and the fetus will breathe and swallow amniotic fluid. Although the organs of the body have begun to form, the fetus unable to live without the womb. Many mothers look at themselves in the mirror at the third month of their pregnancy because they can't wait to see their raised tummy. This is usually the case in the second trimester. 12 weeks embryo THE second trimester at first the fetus starts to move, but it is so small, only 10 cm, and the weight is so small (about 0.1 kg) that the mother still does not bear it. Usually this occurs on the 5th month of pregnancy, when many babies reach 15 cm in height and 0.5 kg in weight. Hair on the body and on the head appear. While many mothers feel uncomfortable in the second trimester, others would specifically consider this the calmest period, because by that time their pregnant nausea is gone, but their belly is too long to make their daily life difficult. 19 weeks old fetus THE third trimester the fetus is fully developed, all body parts and organs have the size it needs to stay alive, the last three months barely "grow" small. At 7 months pregnant, your baby is 35-43 cm long and weighs 1 kg. Thin, red, and wrinkled skin begins to thicken, with a whitish, soft, silky coat, lanugo covering the body, which helps keep the baby's skin adherent, which is responsible for protecting the skin. If the baby were to be born now, You would have a 60% chance of a life with adequate medical care. This chance is already 90% in the 8th month. By this time, the fetus can be up to 45 cm long and 1.5-2 kg. 32 weeks old fetus Month 9 is about the final preparations. The baby's lungs are still developing a lot, losing fat underneath the skin, which removes wrinkles. Much of the lanugo disappears. The baby is approximately 50 cm long, 2.5 to 3.5 kg. He's big and strong enough to be born, and his life is over.Related articles on fetal development:
