Beginning with the flow phase, arrange the biochemical processes in the order in which they occur during the menstrual cycle. 1) fsh and lh stimulate the follicles to develop and the oocyte to produce estrogen. 2) a breakdown of corpus luteum causes progesterone levels to drop. 3) a spike in lh causes the follicle to rupture. 4) the endometrial lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh. 5) rising estrogen levels suppress fsh production and development of other follicles. 6) high progesterone levels maintain the endometrial lining of the uterus. put in order ill give out brainless.
