What is one of the early functions of the placenta during pregnancy?

One of the early functions of the placenta during pregnancy is the secretion of hormones such as estrogen and progesterone. These hormones are crucial for maintaining the pregnancy. Estrogen helps in the development of the fetus and supports the growth of the uterus, while progesterone is essential for preparing the uterine lining to receive and nurture the developing embryo. Both hormones also play a role in suppressing the maternal immune response to ensure that the body does not reject the fetus, which is recognized as foreign.

This early hormonal activity is vital, as it helps to establish a supportive environment for fetal development right from the beginning of pregnancy. It also lays the groundwork for the continued growth and development of the fetus throughout gestation. Understanding this function of the placenta emphasizes its role not only as a support structure but also as an active endocrine organ from early pregnancy.
