What is a primary function of the placenta during pregnancy?

The primary function of the placenta during pregnancy is to transfer nutrients between the mother and fetus. The placenta acts as a vital organ that develops in the uterus, connecting the developing fetus to the mother's blood supply. This connection enables the transfer of essential nutrients such as glucose, amino acids, and fatty acids, which are critical for fetal growth and development.

The efficient transfer of nutrients ensures that the fetus has access to the necessary substances for energy production, cell division, and overall development. Additionally, the placenta also plays a role in transporting antibodies from the mother to the fetus, providing some level of immune protection.

While the placenta does participate in functions such as waste elimination and gas exchange, these are secondary to its crucial role in nutrient transfer. Hence, its primary purpose is to ensure that the fetus receives adequate nourishment to thrive throughout the pregnancy.
