What is the Region of contact between fetus and uterus?

The region of contact between the fetus and the uterus is known as the placenta. The placenta forms from both maternal and fetal tissues and serves as a crucial interface for nutrient and gas exchange, waste elimination, and the production of hormones. It anchors the fetus to the uterine wall and provides a protective environment during gestation. The placenta also plays a vital role in immunological protection for the developing fetus.
