A)menstrual → ovulation → luteal.
B)follicular → luteal → secretory.
C)menstrual → proliferative → secretory.
D)follicular → ovulation → luteal.
E)proliferative → luteal → ovulation.

Accepted Answer

The three phases of the human ovarian cycle are the follicular phase, ovulation, and the luteal phase. The follicular phase is characterized by the development of follicles in the ovary, one of which will eventually mature and release an egg during ovulation. After ovulation, the remaining follicle forms the corpus luteum, which secretes progesterone during the luteal phase to prepare the uterus for potential implantation of a fertilized egg. The menstrual phase occurs if the egg is not fertilized and there is no pregnancy. Therefore, the correct chronological order is follicular → ovulation → luteal.
