. Explain the term Placenta

Best Answer


Placenta is a mechanical and physiological connection between the developing embryo and the maternal tissue. Its primary function is support and nourishment of the developing embryo, but also acts as endocrine gland during pregnancy. The chorionic villi of placenta secrete several gonadotrophins like estrogens, progesterone and HCG (Human Chorionic Gonadotrophin). HCG is a glycoproteinous hormone whose primary function is to maintain the corpus luteum for continued secretion of progesterone so as to maintain the pregnancy. It also controls the normal development of foetus in the mother's womb.
