Answer 1

Ans A( 1):- Inhibitory effect on smooth muscles and endothelial cells of cardiovascular system by vasodilation .

2). Stimulatory effect on GnRH gonadotropin releasing hormone.

Part B These both phase occur after menstruation.folliculogenesis is when ovary is working on develop to egg containg follicles after menstruation for second cycle and proliferative phase is when uterus rebuild the lining which shed off after period.Developing follicles secretes estrogen by which uterus build its lining.Lining of uterus becomes thicker bh estrogen hormone at this phase and thinner at menstrual phase.

Part C The process of transformation of Graffian's follicle and its theca interna into corpus luteum after ovulation is known as luteinization.

And D In follicular phase the follicles mature to release egg..Slightly rising in the level of LH and FSH.In this phase high level lf estrogen and a low level of progesterone

Ovulation:- It is the releasing of egg from mature follicle.During this period LH, FSH is at peak.At this phase uterus lining becomes thinnest.

Luteal phase :- This phase is after ovulation phase when corpus luteum is formed..In this phass high level of progesterone.This progesterone inhibits further secretion of LH and FSH and reforms uterus lining.
