Beginning with the flow phase, arrange the biochemical processes in the order in which they occur during the menstrual cycle.

Tiles

FSH and LH stimulate the follicles to develop and the oocyte to produce estrogen.

A breakdown of corpus luteum causes progesterone levels to drop.

A spike in LH causes the follicle to rupture.

The endometrial lining breaks down and low levels of estrogen stimulate the pituitary to release FSH and LH.

Rising estrogen levels suppress FSH production and development of other follicles.

High progesterone levels maintain the endometrial lining of the uterus.

Sequence

Menstrual cycle is a complex cycle that consists of several processes. Order of occurrence of steps in menstrual cycle are as follows:

1. High progesterone levels maintain the endometrium lining of the uterus.

2. Endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release FSH and LH.

3. FSH and LH stimulates the follicles to develop and the oocyte to produce estrogen.

4. Rising estrogen levels suppress FSH production and development of other follicles.

5. A spike in LH causes follicle to rupture.

6. A breakdown of corpus luteum causes progesterone level to drop.
