The highly vascularized, modified mucosal lining of the endometrium that is established through the process of decidualization. If an embryo does not implant in the decidualized uterus, the lining of the uterus is shed during the next period of menstruation. However, if implantation occurs, the decidua is maintained, and becomes the main source of nutrients for the developing fetus throughout the early weeks of pregnancy, until placenta becomes capable of assuming this responsibility.
The process through which the decidua is established. This process, which occurs during the secretory phase of the menstrual cycle, involves the rapid proliferation and differentiation of endometrial stromal cells, and the development of an extensive uterine vascular system.
A surgical procedure used to remove tissue from the inside of the uterus, often to clear out damaged or infected tissue, to assess the endometrium, or to terminate a pregnancy
