Quizplus · Accepted Answer

The decidua capsularis is the part of the endometrium that covers the implanted embryo and lacks chorionic villi. It is formed by the stretched and thinned endometrial tissue that covers the protruding gestational sac. The other parts of the endometrium mentioned are decidua basalis, which is the layer that lies beneath the chorionic villi and provides nutrients to the developing embryo, decidua parietalis, which covers the rest of the uterine cavity, and decidua albicans, which is the white scar tissue that forms after the pregnancy has ended. Decidua functionalis is the layer that sheds during menstruation.
