After a young embryo implants in the uterus, the uterine lining thickens and becomes richly vascularized to support the growing embryo. A special tissue called the placenta forms, connecting the embryo to the uterine wall and providing it with nourishment and oxygen.
Here’s a more detailed explanation:
Uterine Lining Thickening:
The endometrium, the inner lining of the uterus, prepares to receive and nourish the developing embryo by thickening and becoming highly vascularized. This increase in blood vessels allows for efficient delivery of nutrients and oxygen to the embryo.
Placenta Formation:
As the embryo implants, the placenta begins to develop. This specialized tissue connects the embryo to the uterine wall and facilitates the exchange of nutrients, oxygen, and waste products between the mother and the developing fetus.
Hormonal Changes:
The implantation of the embryo triggers hormonal changes in the mother’s body, including the release of hormones that signal the uterus to maintain its lining rather than shedding it as it would during a typical menstrual cycle.
