Question

Quizplus · Accepted Answer

Progesterone exerts a strong inhibitory influence on the uterine musculature, which helps to maintain pregnancy by preventing premature contractions and expulsion of the fetus.

Answer: C
 Progesterone promotes duct development in the breasts, which prepares them for lactation during pregnancy and after childbirth.

Answer: D
 High levels of progesterone initiate the onset of labor by antagonizing the inhibitory effects of estrogen on the uterine musculature and promoting the production of oxytocin, which stimulates uterine contractions.

Therefore, the best choices are A and C.
