प्रश्न
Name the function of the following:
Endometrium
Advertisements
उत्तर
It is the uterine mucous membrane, which thickens and becomes more glandular as the menstrual cycle progresses and has an enhanced blood supply. If embryo implantation does not occur, the endometrium undergoes a decline and loses most of its tissue during menstruation. If a pregnancy is confirmed, the endometrium develops into the decidua, which is shed after birth.
