After a woman finds out that she is pregnant, all her thoughts are only about the baby and his development. Meanwhile, the fetus in her belly grows and changes every day, so that in 9 months it will be born.
Instructions
Step 1
At the 6th week of pregnancy, the fetus is actively developing and forming. The most important organs and life support systems of the crumbs continue to be laid. Therefore, any negative effects will not only harm the fetus, but can also become destructive. At the 6th week of pregnancy, the fetus is very small - its length is about 4-9 millimeters, and its weight is all 4-4.5 grams. The heart of the baby beats very quickly and is 2 times faster than the heartbeat of the mother. True, the heart has not yet been finally formed; it will divide into atria much later.
Step 2
During these seven days, the embryo first forms two tubercles in the place where the arms will later be, and two more where the legs will form in the future. Cartilage tissue begins to form. Over time, it forms tendons, bones, muscles, and later on, the chest. The "face" of the fetus this week also undergoes changes: the rudiments of milk teeth appear, the auricles are formed, the baby's nose, mouth and jaw are already noticeably looming. The eyes are still in the form of rudiments. True, they change their position. If earlier the eyes were on both sides of the embryo's head, now they are getting closer. But when compared with other organs, the eyes are still very large.
Step 3
At this time, the intestinal tube of the fetus is actively developing. A little more and the intestines, excretory, digestive, and respiratory systems will be formed. The laying and development of the lungs, stomach, liver, pancreas begins. One of the most important organs of the immune system, the thymus, begins to form. Particular attention at the 6th week of pregnancy in the development of the fetus requires the moment of tightening the neural tube. The brain begins to form from it. Brains and depressions in the brain appear already at this stage. The muscles and heart of the fetus are already under the control of the brain. Along with this, nerve cells are actively dividing. Therefore, it is very important for a pregnant woman to take care of her health, as well as her emotional state. You need to try to exclude any worries and adhere to the doctor's recommendations. These points will be of key importance in the future development of the fetus.
Step 4
It is worth saying that it is at this stage of pregnancy that the placenta is attached to the inner wall of the uterus. Starting at 6 weeks, the placenta will form at a rapid rate. It is still small, but by the end of pregnancy, the weight of the placenta will reach 800 grams.
