Explanation

During proliferative phase, the follicles start growing in size under the influence of Follicle stimulating Hormone (FSH). Hence, this phase is also called follicular phase.
During secretory phase, corpus luteum secretes progesterone that helps to thicken the endometrial lining. Due to the persistence of corpus luteum, this phase is also called luteal phase.
Menstruation or bleeding occurs due to the breakdown of endometrial lining in the absence of pregnancy. During this phase, corpus luteum regresses and progesterone level decreases.
