What to Expect at 8 Weeks Pregnant. By the 8th week of pregnancy, the brain and the nervous system of the fetus are already completely formed. At ultrasounds, it is already possible to examine the

baby`s face, to distinguish his mouth, nose, eyes and lips. There are two ways samples are collected: Transcervical: An ultrasound guides a thin catheter through the cervix to your placenta. The chorionic villi cells are gently suctioned into the catheter. This is the most common method. The placenta is a unique organ because it is only present during pregnancy. It nourishes the fetus while it is developing in the womb and is then expelled after the baby is born. Vasa previa is a condition which arises when fetal blood vessels implant into the placenta in a way that covers the internal os of the uterus. Pregnancy weeks are grouped into three trimesters, each one with medical milestones for both you and the baby. First trimester. A baby grows rapidly during the first trimester (weeks 1 to 12).The Estriol (E3), also spelled oestriol, is a steroid, a

weak estrogen, and a minor female sex hormone. It is one of three major endogenous estrogens, the others being estradiol and estrone. Levels of estriol in women who are not pregnant are almost undetectable. However, during pregnancy, estriol is synthesized in very high quantities by the placenta and is the most produced estrogen in the body The uterus (from Latin "uterus", plural uteri) or womb is a major female hormone-responsive secondary sex organ of the reproductive system in humans and most other

mammals.In the human, the lower end of the uterus, the cervix, opens into the vagina, while the upper end, the fundus, is connected to the fallopian tubes.It is within the uterus that the fetus develops during gestation. During the first stage of labour, your cervix needs to dilate from 0 cm to 10 cm. During pregnancy, your cervix is closed. During labour, your cervix

widens (dilates) to 10 cm to allow for the birth of your baby. Fetal alcohol syndrome could arise when a woman drinks alcohol in the course of her pregnancy. For years, the syndrome has been the leading cause of birth defects and mental retardation. #include "headerA.incl" Umbilical Cord Issues/Delayed Cord Clamping #include "headerB1.incl" See also: Umbilical Cord Care; Subsections on this page:
