When a fertilized egg implants in a woman's uterus, the placenta begins to develop.
Formation of the placenta begins in the second week after the fact of conception.
During this period all organs and systems are laid, the placenta begins to function actively.
It penetrates the placenta, begins to multiply and affects the tissues of the fetus.
Also during fourth week of pregnancy, your placenta begins to form.
The placenta begins to change hormones, rebuilt various physiological processes.
Around the fourth week of pregnancy, the placenta begins to develop.
During this period, the placenta begins to function fully, which connects it with the mother.
This is necessary in order for the embryo to have something to eat after conception until the placenta begins to work.
The thing is that the placenta begins to function actively from the second trimester(after 11-13 weeks).
At some point between pregnancy week 11 and week 12,the baby's blood will start to circulate between the uterus and the baby as the placenta begins to function.
Many experts believe this is because the placenta begins producing hormones of its own at this time.
For example, an oxygen deficiency in your baby, a digestion that does not start, complete exhaustion of the mother,an infection or the placenta begins to come loose.
From the second trimester, the placenta begins to function, pregnancy, as a rule, stabilizes, passes toxicosis.
Because the placenta begins to secrete hormones, you will get a positive pregnancy test and may have early pregnancy symptoms, but an ultrasound will show an empty gestational sac.
As a result, the endothelium is damaged,the compensatory mechanisms gradually disappear and the placenta begins to“artificially” increase the missing pressure to improve the blood supply to the fetus.
This is when the placenta begins producing large quantities of the hormones that cause insulin resistance.
The yolk sac by the 12th week is almost completely neutralized,since by this time the placenta begins to ripen, which will perform all the same functions and provide the fetus with nutrients and all the factors necessary for normal development.
Normally, the placenta begins to develop at a distance of at least 6 cm from the internal pharynx of the uterus(the inside of the cervix), otherwise doctors diagnose"low placentation," and this poses a number of problems during pregnancy, such as bleeding and improper presentation of the fetus, which often lead to rapid delivery, and in severe cases- even to the death of the mother and child.
This happens at the beginning of the second trimester of pregnancy(it"starts" from the 14th week), when the placenta begins to work in full force and becomes a kind of barrier between a woman and a child, thereby smoothing out some problems from direct"communication" of the future mother and baby.
Once a woman's placenta begins to secrete hCG, it doubles the amount it produces about every 48 hours.
After 40 weeks, the viability of the placenta begins to fade and the baby may not receive the nutrients and oxygen needed to sustain healthy growth.
It is at this point in time that the placenta begins to work at full strength and becomes a kind of barrier between a woman and a child, thereby smoothing out some problems from direct"communication" of the future mother and baby.
