Do you know how to discharge you baby
The most commonly heard phrase during pregnancy, than the "what to eat more nutritious, the baby will grow up well." Although familiar with this truth, but the mothers of the baby belly for how "to eat, drink?" How "pull, Caesar?" Moms I'm afraid this little knowledge, lay to it!
Most have heard of moms and absorption of oxygen metabolism of the fetus is carried out through the umbilical cord, but fetal nutrition and provide an important source of protection - the placenta, but very limited understanding of some of the mother's placenta and umbilical cord will be even function mingled together. Below, we look at mothers with placental what it is now!
The placenta is how to generate it?
Fertilized egg of about 7 to 9 days in the thickening of the endometrium on implantation, implantation began after a series of cell division, differentiation will produce:
Fetal membrane
1. Yolk sac in 2 to 3 weeks to help deliver nutrients to the embryos, 3 to 6 weeks during the manufacture of the original blood cells, 7 weeks into the umbilical cord, and then gradually degraded.
2. Amniotic membrane produces amniotic fluid protect the fetus.
3. Chorionic chorionic below to continue to grow embryonic and uterine wall depth of depression, followed by the formation of the placenta.
4. Allantoic degenerate into the umbilical cord in the last three vessels and median umbilical ligament.
All embryonic layers of fetal tissues, organs, systems originate at the
Embryo development to the 4 to 5 weeks when the original placenta, the placenta has been formed about 8 weeks, the umbilical cord also appeared.
At this time a human embryo has been gradually taking shape, the major organs such as heart, lung and kidney development have been formed, we would call after 9 weeks of pregnancy the embryo as a "fetus."
Placenta will take over after the formation of the original task by the yolk sac to provide nutrients, and begins to secrete progesterone and other hormones, so that the body maintain normal pregnancy. Development of the placenta after 16 weeks to full maturity, pregnancy has begun to enter the stable.

Early Signs of Women Menopause
In fact surely every woman should know that we will experience from adolescence to menopause menstrual menstruation stop the entire process. So what exactly women for early signs of menopause? Here we come to know in detail.
Experts pointed out: women in general from 30 years of age, ovarian function begins to gradually decline and shrinking follicles absorb the nutritional deficiencies, slow to mature, the amount of estrogen and progesterone secretion decreased, not time of endometrial thickening, loss, menstruation naturally can not come on time. At this time women are closer to menopause.
1, too few menstrual
The most common reason is that there is no ovulation. No ovulation occurs most frequently at the beginning of the first year of menstruation, menopause fast few years, too much pressure, the normal circumstances, the need for timely conditioning, and relax the pressure, maintaining a good mood, you can improve and restore normal menstruation. Because too few menstrual endometrial adhesions, although ovulation, but can not form the endometrium, menstruation, of course very small.
2, abnormal menstrual cycle
Menstrual cycle to come too close or too long time, the most common cause is not the normal follicular maturation, resulting in abnormalities of ovulation. Immature follicles without ovulation, there is no "yellow body", ovarian secretion of estrogen and progesterone on the endometrium of the control is not complete. Endometrium is too thick, it will show peeling unstable, irregular menstrual cycles, abnormal volume. This lack of ovulation is usually delayed for a long time period, endometrial spalling is not clean, the cumulative long-term, there will be changes in the risk of endometrial cancer.
3, excessive menstrual
Blood clots in the big, often dirty linen underwear, sanitary napkins have to use the king, dizziness phenomenon, is the blood too much. No ovulation, resulting in too little or too long menstrual flow did not come when the endometrium is not completely falling off due to become unstable very thick, is formed when peeling off a lot of menstruation. Instantaneous flow a lot of blood, the body will not support, may be unconscious, is very dangerous.
