Along with gas exchange and nutrient transfer, the placenta produces many hormones necessary for normal pregnancy.
These include (select all that apply):
Human chorionic gonadotropin (hCG).
Testosterone.
Insulin.
Estrogen.
Progesterone.
Correct Answer : A,D,E
Choice A rationale
Human chorionic gonadotropin (hCG) is produced by the placenta, maintaining the corpus luteum and promoting progesterone production crucial for sustaining pregnancy.
Choice B rationale
Testosterone is not produced by the placenta; it is primarily synthesized in the testes and ovaries and not involved in normal pregnancy hormone production.
Choice C rationale
Insulin is not produced by the placenta; instead, it is secreted by the pancreas and regulates blood glucose levels, not directly linked to pregnancy hormones.
Choice D rationale
Estrogen is produced by the placenta, contributing to the development of female secondary sexual characteristics and maintaining the uterine lining during pregnancy.
Choice E rationale
Progesterone is produced by the placenta, supporting the uterine lining's maintenance, preventing contractions, and creating a suitable environment for fetal development.

Correct Answer is B
Explanation
Choice A rationale
Although the placenta acts as a partial barrier, it does not keep out all harmful substances, allowing some to cross and affect fetal development.
Choice B rationale
One of the placenta's early functions is producing hormones like human chorionic gonadotropin (hCG), estrogen, and progesterone, making it act as an endocrine gland.
Choice C rationale
The placenta does not thin out; it remains robust and increases in thickness to support the growing fetus and facilitate nutrient and gas exchange.
Choice D rationale
While optimal blood circulation through the placenta is crucial, this statement lacks detail on the specific structural and functional aspects of the placenta.
Correct Answer is ["A","C","D"]
Explanation
Choice A rationale
Pitocin is used for augmentation of labor to increase uterine contractions' frequency and strength, enhancing labor progression in cases where labor is slow or stalled.
Choice B rationale
Pitocin does not increase prolactin receptor sites; instead, it focuses on enhancing uterine contractions during labor and addressing postpartum hemorrhage.
Choice C rationale
Pitocin is used for induction of labor to stimulate uterine contractions and initiate labor in women who need medical intervention for various reasons.
Choice D rationale
Pitocin helps decrease bleeding after delivery by promoting uterine contractions, which aid in reducing postpartum hemorrhage and expelling the placenta.
