Question

Quizplus · Accepted Answer

The corpus luteum secretes both estrogens and progesterone in order to maintain the thick lining of the uterus and prevent menstruation, which could cause the loss of the implanted embryo. Choice C, human chorionic gonadotropin, is secreted by the developing embryo to maintain the corpus luteum and continue progesterone production, but it is not initially secreted by the corpus luteum itself. Choices A and B are hormones secreted by the pituitary gland, and are not directly involved in the maintenance of an implanted embryo.
