### Role of the Decidua in Early Pregnancy **Decidua** refers to the modified endometrial lining of the uterus during pregnancy. It plays a crucial role in the implantation of the blastocyst, supporting the developing embryo, and facilitating the interaction between maternal tissues and the placenta.

Decidualization is essential for establishing a supportive environment for the developing embryo and placenta. Understanding these processes is crucial for healthcare professionals involved in reproductive health, obstetrics, and gynecology, as they can significantly impact pregnancy outcomes. Visualizing these changes through histological slides can enhance understanding and clinical practice regarding implantation and early pregnancy management.
