Decidua

The decidua is a specialized membrane that forms in the uterine cavity during pregnancy. It consists of transformed endometrial cells and plays an important role in the process of embryo implantation and placental development.

The name "decidua" comes from the Latin word deciduus, which means "falling away." This is due to the fact that after childbirth this membrane is torn away along with the placenta and excreted from the body.

Main functions of the decidua:

1. Ensuring implantation and nutrition of the embryo in the early stages of development, before the formation of the placenta.

2. Regulation of the processes of trophoblast invasion and remodeling of the spiral arteries of the uterus during placentation.

3. Creation of an immunological barrier between the mother and fetus, preventing embryo rejection.

4. Production of hormones and biologically active substances necessary to maintain pregnancy.

5. Separation of the placenta after childbirth and healing of a wound on the uterus.

Thus, the decidua plays a key role in the successful course of pregnancy and childbirth. Disturbances in its development and functioning can lead to complications, such as miscarriage, placental abruption, and bleeding.

The decidua (membrana decidua) is a thin membrane that covers the amniotic sac in the uterus. It consists of decidual cells that produce proteins, hormones and other substances necessary for the development of the fetus and the preparation of the uterus for childbirth.

The decidua plays an important role in the development of the fetus and the preparation of the uterus for childbirth. It protects the fetus from infections and other external factors, and also promotes the development of the placenta and an increase in the volume of the uterus. In addition, the decidua produces hormones that regulate the menstrual cycle and preparation for childbirth.

However, in some diseases, such as miscarriage, the decidua can become a source of infection and inflammation. This can lead to pregnancy complications and even miscarriage. Therefore, it is important to monitor the condition of the decidua and undergo regular examinations by a doctor.
