The embryo at the 7th week of pregnancy can already be rightfully called a fruit, that is, a small man. The embryo at 7 weeks old looks like a newborn baby, although until the end of the formation of all organs is still very far away.
Fetal baby at 7 weeks old
The embryo in 7 weeks, of course, does not look much like an adult person. The size of the fetus barely reaches 10 mm, and its weight does not hold up to one gram. At week 7, the eyes are still located on the sides of the head, but the iris has already begun to form. In the outline of the spout, you can consider tiny nostrils.
Handles of the embryo at 7-8 weeks already bend at the wrists, also begins to stand out forearm. In addition, between the legs appears tubercle, which is the beginning of the development of external genitalia. At week 7, the baby still has a small "tail" that will disappear a little later.
Fetal development at week 7
At the age of 7 weeks, the brain actively develops. Also, the heart system is formed - the baby already has a left and right atrium, and very soon the heart from the middle of the thorax will move to its rightful place. In addition, even if you place an ultrasound sensor on your mother's abdomen, at 6-7 weeks you can listen to the heartbeat of the fetus .
Although the baby will make his first breath only after birth, the respiratory system - lungs and bronchi now develops. Large changes occur in the intestine - the formation of the large intestine ends, and the pancreas starts producing insulin.
At the end of 7 weeks, the umbilical cord will be fully formed, which will take on all the functions to ensure the fetus with oxygen and nutrients. The placenta becomes denser, a barrier appears that protects the baby from certain harmful toxins and substances found in the mother's body.
7 weeks of pregnancy for the future mother
The first trimester of pregnancy is unlikely to be a pleasant time. The reason for this is toxicosis, which occurs in every second woman, as well as hormonal changes in the body. And although the belly still can not be seen as such, a woman can gain a couple of kilograms, of course, if the constant bouts of nausea give an opportunity to eat normally. Because of toxicosis in this period, there may also be a slight weight loss. In any case, at the 7th week, the correct full nutrition of the pregnant woman in the first trimester is needed, as well as an additional course of vitamins and minerals.
