Answer 1

Menstrual phase, Follicular phase, Ovulatory phase, Luteal phase

Explanation:

The menstrual cycle consists of the following phases in order:

1. Menstrual phase (uterine lining shedding).
2. The ovary’s main follicle develops into a fully grown Graafian follicle during the follicular phase: maximum amount of estrogen.
3. LH and FSH levels peak during the ovulatory phase, which is when an egg is released as a result of the Graafian follicle rupturing.
4. Progesterone is secreted during the luteal phase, when ruptured Graafian follicle cells swell and form a golden corpus luteum. The corpus luteum degenerates into the corpus albicans, a whitish mass, and the progesterone level falls if the ovum is not fertilized.
