Explanation by: Admin

The placenta is a temporary organ that develops during pregnancy.

It is formed by the interaction between the foetal chorionic tissue and the maternal uterine tissue.

The placenta functions as an interface for nutrient exchange, gas exchange, and waste removal between the mother and the developing foetus.

It also produces hormones like hCG (human chorionic gonadotropin), progesterone, and estrogen to support pregnancy.
