The primary function of the placenta is to provide nutrition and oxygen to the fetus. The placenta acts as an interface between the mother and the developing fetus, allowing for the exchange of nutrients, gases, and waste products. Through a network of blood vessels, the placenta ensures that the fetus receives essential nutrients such as glucose, amino acids, and fatty acids, as well as oxygen, which are vital for its growth and development. In addition to these roles, the placenta also helps to filter out some waste products from the fetal blood, although that is a secondary function to its role in nourishment and oxygenation. Thus, the placement and function of the placenta are critical for sustaining the fetal environment throughout pregnancy.
