You eat with your mouth, breathe with your nose and lungs. But the fetus can’t do that for certain reasons. He’ll have to wait for the birth to feed and breathe like you. For now, it takes the nutrients and oxygen necessary for its nutrition and development through two or gan: the last and umbilical cord. Doctors call them additional organs. These are additional and transient organs, because they don’t work after birth. The final and umbilical cord complement each other, but they both have separate assignments. Finally, he takes the necessary oxygen and food from his mother’s blood, and the umbilical cord delivers to him.
Placenta means Latin cake. It really resembles a placenta sponge-shaped cake. Let’s go a little bit back to see how Son formed. When the egg nested, you saw that the small fibers of the outer membrane dive into the uterine mucosa, like the roots of a tree. These fibers plunging into the mother’s abdomen were taking the nutrients necessary for the development of the egg. These fibers, which were initially small, multiply over time. Towards week 4, the outer membrane of the egg fills with these fibers in the form of thin hairstrands. This primitive organization, which is used to feed the egg in the first weeks, is not enough to develop the embryo over time. This time, the mother’s body and eggs set up a small center. We call this the end. The hair of part of the outer membrane disappears, the membrane becomes polished and glued to the uterine mucosa. In the other section, on the side of the hair, the hair develops, gathers together and dissects the uterine mucosa more. In this section, the hairs of the egg on the one hand and the uterine mucosa on the other hand create the end together. So son has labor for both your mother and foetus. The last fibers (or feathers) are like small trees. The body and branches are covered with a thin membrane. In each fiber, there are small veins transmitted by the umbilical cord, where the blood of the embryo circulates. These fibers are surrounded by mother’s blood, which constitutes small lakes. This blood always comes through the veins to the uterus with fresh, nutritious substances and oxygen.
So in the last, the blood of the embryo meets the mother’s blood, but they don’t interfere. The blood of the embryo is in the fibers, and the mother’s blood is outside the fibers. It’s very important that you understand that. Because many mothers think their blood is directly in the blood of their children. If it was like that, the blood type would be the same. Besides, the blood is different. They’re often in separate groups. Not only the mother’s blood that passes through the fibers, but some of the necessary substances to the child carrying oxygen and blood pass the membrane covering the fibers and enrich the child’s blood. In the opposite direction, the remains and gas thrown by the fetus pass through carbonic.
The last works like a good filter. Besides oxygen, he goes through:
- Substances grounded and digested by the mother (water, calcium, iron, salt. phosphorus, sulfur, sugar, nitrogensubstances, etc.). All this goes directly into the pocket.
- Raw materials (albumin. oils, etc.) that end changes before sending it to the fetus.
But this factory, named after its last name, also has advanced views. When a lot of nutrients come, it stores. The last is a real store where the fetus will take and use its needs when necessary. He’s as cautious as he is forward-thinking. It covers all microbes, most viruses, and the poisons that come with mother’s blood. However, no matter how much it does not pass, it is still syphilis. Some bacteria, such as chickenpox and coca basil, can pass through here. For this reason, these diseases are dangerous during pregnancy. These should be avoided with violence or treated immediately when seen. The last to stop certain poisons, as well as some antidotes, substances extracted by the mother’s blood to combat germs, for example, if the mother is typhany, she passes the antidote to the last child, which instills the child against typhany for up to 6 years after birth. But in a way, the antidote will hurt the child. This occurs when your mother’s blood gru-* is this Rh negative and her father is Rh positive. Medications taken by the mother are often turned back by the last, but some pass, so it is necessary to be cautious. Watch what’s said in the meds section.
Many vitamins pass the end easily. On the contrary, carbonic acid and residues pass from the fetus to the uterus. The fetus looks at the take more than it does. It can also give insulin to the mother if needed (the drug of diabetes). It’s a miracle of the fetus. The filter, factory, store and protective son has another paper: It extracts a large amount of estrogen and pre-projectster hormones. 3. or 4. At the end of the month, as the yellow object completes its mission, the last takes its place and begins to remove hormones. Eggs have now gained their freedom and began to see their own needs.
The last pocket, which is attached to the uterus with fibers, is connected by the umbilical cord. With the last means, oxygen and nutrients taken from the mother’s blood come to the fetus with the umbilical cord. At the same time, this cord brings the residues to the end, and the end gives them to the mother’s general bloodstream. The umbilical cord is similar to the pipe that fuels a flightplane. It’s some kind of gelatinous tube, and it passes through two clean blood vessels and a large dirty blood vessel. These veins connect your embryo and end’s capillaries. Most of the umbilical cord consists of amnios cells, one of the side membranes that cover the egg. The cord begins to develop from the middle of the embryo’s abdomen. The average length is 50 cm. But sometimes it’s a. It’ll take a foot and a half. If it’s too long, it’s wrapped around the fetus, especially the neck. Like the last one, the umbilical cord is on the 3rd floor. completely shaped per month. At birth, the doctor cuts off the umbilical cord and gives the child all his freedom.
Dice Of The Egg
The foetus, which is fed by its last vehicle and connects it with the umbilical cord, is protected by two dice. The first is the corionme, the outermost; The second is made up of the first cells of the egg, such as a plastic or silk bag of amnios. At first, although this dice completely covers your embryo, it is gradually separated by making a space from it. The gap grows and fills the uterus. This gap fills a white and light-colored liquid extracted by amnios. This is called amniotic fluid or water. In six months, water is about a liter. When the birth gets closer, it stays half a liter.
The water always ensures that there is an equal liquid around the fetus and that the fetus does not stick to the edge of the uterus. In the middle of the water, the fetus floats like a fish. That’s how he avoids all the pressures of the outside world. In fact, if the mother gets hit or falls, the fetus is well protected, so it won’t be affected by the blow.
At birth, liquids and dice produce a bag. This bag, which has water in it, allows the uterus to expand. When the bag tore stoming and releasethe fetus, the birth is close. ?
