How will you justify that placenta acts like an endocrine tissue?

The placenta acts as an endocrine tissue by producing and secreting various hormones that are crucial for maintaining pregnancy and supporting fetal development. Key hormones include human chorionic gonadotropin (hCG), progesterone, and estrogen, which regulate maternal metabolism, immune tolerance, and uterine conditions. These hormonal functions are essential for sustaining the pregnancy and facilitating the growth and development of the fetus, similar to the roles of traditional endocrine glands. Thus, the placenta plays a vital endocrine role in coordinating maternal and fetal physiology.
