Question

Name the hormones secreted by human placenta.

Answer 1

Hint: The placenta is a momentary organ that ties the growing fetus through the umbilical cord to the uterine wall to permit nutrient uptake, thermo-regulation, waste removal, and gas switch over via the mother's blood supply; to combat against internal infection, and to create hormones which favor pregnancy.

Complete answer:
Hormones emitted by the placenta are Estrogen, Progesterone, hCS, hPL&hCG. The placenta is an endocrine gland that is solitary present at the time of pregnancy. hCG or the human chorionic gonadotropin is liberated in a superfluous amount in early pregnancy. Its presence in urine is utilized for the pregnancy test. hCS or human placental somatomammotropin is also known as placental lactogen. It acts as a mild growth hormone.

Estrogen is a steroid hormone that is created in the syncytiotrophoblast of the placenta, with the placenta becoming the key source of this hormone around during the ninth week of pregnancy. Progesterone is another main steroid hormone that is formed by the placenta. Human Chorionic Gonadotropin (hCG) is a pregnancy hormone that is crucial to both the creation and maintenance of the pregnancy, playing a great role in multiple facets of the pregnancy process.

Chorionic somatomammotropin (hCS), also called placental lactogen hormone (LH) is a lactogenic protein. Human placental lactogen (hPL) is a hormone manufactured by the placenta, the organ that matures during pregnancy to aid feed the growing baby.

Note: The appendage which acts as placenta consists of two parts- the fetal placenta (Chorion frondosum), which matures from the similar blastocyst that creates the fetus, and the maternal placenta (Decidua basalis), which grows from the maternal uterine tissue. It metabolizes the number of substances and can emit metabolic products into maternal or fetal circulations. The placenta is ejected from the body upon the birth of the fetus.
