decidua

Womb's gestational lining

The decidua is the modified uterine lining during pregnancy, formed after a fertilized egg implants.

This specialized tissue nourishes the embryo and later becomes part of the placenta.

It sheds after delivery—the name comes from a Latin word meaning "falling off," like deciduous leaves.

The doctor examined the decidua for signs of abnormality.
