What is the difference between gestational sac and gestational sac?

For those who are preparing to become pregnant, it is necessary to learn more about some pregnancy-related terms, which can be of some help to themselves. For example, the gestational sac and the gestational sac, this is something people must understand clearly. Many people think that the gestational sac and the gestational sac are the same. In fact, this is not the case. There are certain differences between the two. Let me give people a detailed introduction to the difference between the gestational sac and the gestational sac.

The gestational sac (GS) is the earliest ultrasound diagnostic basis for confirming pregnancy. The appearance of a gestational sac in the uterus is the earliest phenomenon in ultrasound diagnosis. It can occur at 5 weeks of pregnancy. Rhythmic fetal heartbeat, embryo and fetal movement can be seen in the gestational sac. It can be diagnosed as early pregnancy and live fetus.

Within the outline of the enlarged uterus, a round or oval halo is seen with clear boundaries and an echo-free area within. The appearance of a gestational sac in the uterus is the earliest phenomenon in ultrasound diagnosis. It can occur at 5 weeks of pregnancy. Rhythmic fetal heartbeat, embryo and fetal movement can be seen in the gestational sac. It can be diagnosed as early pregnancy and live fetus.

After the fertilized egg implants, the endometrium rapidly undergoes decidua changes. The decidua covers the fertilized egg, surrounding the fertilized egg between the uterine muscle and the endometrium, forming a closed cavity. The fertilized egg develops into a fetus in this relatively closed sac, which is medically known as the gestational sac (gestational sac is also known as the gestational sac). In the early stages of embryonic development, the amnion is closely related to embryo formation. The fluid in the gestational sac shown on ultrasound is mainly chorionic fluid, which represents the chorionic cavity. As early pregnancy progresses, the amniotic cavity expands until about 10 weeks of pregnancy, when the chorionic cavity gradually disappears and the amnion and chorion fuse.

The gestational sac is the primitive placental tissue, a small embryo wrapped by the amniotic membrane and vascular network. The gestational sac is the initial form of pregnancy. At that time, the fetus has not yet formed, and the fetal heartbeat is already there when the embryonic bud appears.

The gestational sac is also a product of ectopic pregnancy. The fertilized egg fails to enter the uterus at 7 days due to certain factors such as inflammation and adhesion. Ectopic pregnancy usually causes heavy bleeding, and generally the fetus cannot survive. The mother of the little baby was experiencing an intrauterine pregnancy, but due to poor development of the uterus, the gestational sac broke through the weak top of the uterus and entered the abdominal cavity. The villi around the gestational sac sought nutrients everywhere in the abdominal cavity and then supplied them to the fetus through the placenta. Usually, such a fetus will die within two months because it has no protection from the uterine environment and lives in an extremely harsh environment with poor nutrition.
