The placenta is a vital organ that develops during pregnancy, connecting the developing fetus to the uterine wall in the mother's body. It serves as a lifeline, providing nourishment, oxygen, and waste elimination for the growing fetus. The placenta also facilitates the transfer of antibodies and hormones between the mother and the fetus. It acts as a barrier, protecting the fetus from certain infections and harmful substances. The placenta plays a crucial role in maintaining a healthy pregnancy and is expelled from the body after childbirth. Understanding the functions and importance of the placenta is essential for ensuring the well-being of both the mother and the developing baby.
