During pregnancy, every organ in the body will change.Muscles and joints are shifted, squeezing each other, accelerated heartbeat, and blood and arteries in the vein.
These changes caused by a hormone (hormone) have emerged at the beginning of pregnancy. In the days after fertilization, embryos are implanted into the endometrium of the uterine, because his DNA is incomplete as his mother.It is deemed to be an intruder, just like treating bacteria or other harmful microorganisms, and immediately attack and destroy it. His mother ushered in challenges. His immune system needs to protect her and the fetus, but it cannot be done as before pregnancy.It is not as simple as reducing the immune response. On the contrary, this is a complex interaction that we only understand, involving many different types of immune cells, some of which seem to protect the tire attack from other immune cells.
The body will also form antibacterial plugs made of mucus on the cervix.With the increase of pregnancy, the uterus expands upward with the growth of the fetus. In order to free up the space, the body secretes hormones called progesterone and relaxin.The muscles will also relax, which makes them slow, and the waste residue slows through the pipeline, resulting in constipation.
At the same time, the muscle on the top of the stomach may cause the stomach acid to the esophagus and throat, causing the stomach burning and reflux. These hormones will exacerbate the pregnancy vomiting caused by choricular gonad hormones.time.
The growth of the uterine growth to the diaphragm, that is, each breathing will cause the chest to dilate and shrink the muscles. This limits the range of activity of the diaphragm. Can progesterone as compensation hormone can be used as a breathing stimulant to make pregnant women breathe faster, so she and the baby are bothIt can get enough oxygen with less lung capacity, all of which can make pregnant women feel short of breath.
At the same time, the kidneys will produce more red blood cells, which is a hormone that increases red blood cells.The kidneys will still retain excess water and salt to accumulate blood, instead of filtering them out of urine. The blood capacity of pregnant women increases by more than 50%, but the blood is also diluted because the red blood cells have only increased by 25%. Usually, we will pass throughThe iron in the food is to create blood cells, but during pregnancy, the fetus is also absorbing nutrients from the mother’s food to establish their own blood supply mechanism.The iron and other nutrients obtained by the mother have decreased. The heart must work harder to supplies these blood to the body and the placenta, and the heartbeat of the pregnant woman accelerates, but we still do not fully understand the changes in blood pressure during healthy pregnancy. This is an important thing.The topic, because some of the most serious complications are related to the heart and blood, the uterine dilation may compress the veins and cause the legs and feet to accumulate liquid. If these liquids are pressed on the large vein called the lower cavity vein, it may interfere with it.The blood flows to the heart. At this time, if the pregnant woman stands for too long, the blood pressure will decrease and dizzy.
Some of the changes before childbirth began to fall back shortly before childbirth, reducing the pressure on the intervasal membrane so that pregnant women can breathe deeply. When the amniotic fluid is ruptured during delivery, the excess liquid in the body will lose a large amount of uterus in the uterus before childbirth.
Pregnancy will also affect the brain, just like other parts that affect the body, but people have little influence on these influences. Recent research shows that through brain scanning, it can be found that the brain of pregnant women and novice mothers has differences.To help mothers enhance parenting ability. For example, if babies do not speak, the mother improves the ability of reading.There are not many research on how to affect the brain during pregnancy, which highlights a common fact. Almost all pregnancy research in history only revolves around the fetus rather than pregnant women.The difference is very different. New research will help us understand the reason and develop effective treatment methods when necessary. At the same time, the reaction of each pregnant woman is different. If you have any specific problems, please consult a doctor.
Today, we are at a exciting turning point, because more and more research has begun to pay attention to pregnancy biology.In the past 40 years, there are more than 5 million babies who have been fertilized in vitro. How did this do?We can only lament the magic of technology.
