Question

The longest part of the ovarian cycle occurs after ovulation and is called the _____ phase.

a) Follicular
b) Luteal
c) Menstrual
d) Proliferative

Answer 1

The luteal phase is the phase that follows ovulation in the ovarian cycle, lasting about 14 days, characterized by the activity of the corpus luteum which produces hormones to maintain the uterine lining.

Step-by-step explanation:

The longest part of the ovarian cycle that occurs after ovulation is called the luteal phase. The luteal phase is the third, final stage of the ovarian cycle, and it usually lasts about 14 days in a 28-day menstrual cycle. FSH and LH stimulate the transformation of the ruptured follicle into a structure known as the corpus luteum, which then produces estrogen and progesterone. These hormones are critical for maintaining and building the uterine lining, preparing it for a potential pregnancy. If the egg is not fertilized, the corpus luteum degenerates, leading to the drop in progesterone and estrogen levels and the onset of menstruation.
