Question

Quizplus · Accepted Answer

During the process of involution, the uterus returns to its prepregnant size. This occurs due to the decrease in size and elimination of the placenta and other pregnancy-related tissues, as well as the contraction of uterine muscles. Option A is incorrect as cervix opening and amniotic sac rupturing happen during labor. Option B refers to the delivery of the placenta and is a separate process from involution. Option C is incorrect as the levels of estrogen and progesterone decrease steeply during the postpartum period.
