Quizplus · Accepted Answer

During the luteal phase, the follicle that released the egg during ovulation turns into a glandular mass of cells called the corpus luteum. The corpus luteum produces hormones such as progesterone to prepare the uterus for a potential pregnancy.

Answer: B 
 The endometrium, or lining of the uterus, breaks down during the luteal phase if no pregnancy occurs. This leads to menstruation as the tissue and blood are discharged through the cervix.

Answer: C 
 The corpus luteum produces progesterone which helps to maintain the thickened uterine lining during the luteal phase. If fertilization does not occur, the corpus luteum degenerates causing a decrease in progesterone levels leading to the shedding of the uterine lining.

 Luteinizing hormone (LH) is responsible for triggering ovulation which occurs during the follicular phase of the menstrual cycle. Its levels decrease after ovulation, therefore LH is not actively secreted during the luteal phase.
