Placenta
The placenta is a vital organ that forms during pregnancy in mammals, including humans. It is a specialized interface between the mother and fetus that mediates the exchange of gases, nutrients, hormones, antibodies and waste products. Ultimately, it provides the fetus with oxygen, nutrition and protection. The placenta is also responsible for secreting the hormone progesterone, which is necessary for maintaining the uterine lining during pregnancy. It is therefore essential for a successful pregnancy outcome.
