Question

What are the changes that the ovaries and the uterus undergo during the female reproductive cycle

Answer 1

The female reproductive cycle includes the ovarian and uterine cycles, the hormonal changes that regulate them, and the related cyclical changes in the breasts and cervix.

phases: the menstrual phase, the preovulatory phase, ovulation, and the postovulatory phase

preovulatory phase, events in the ovaries:

secondary follicles in the ovaries start to discharge estrogens and inhibin; estrogens and inhibin emitted by the dominant follicle diminish the emission of FSH, which causes other, less very much created follicles to quit developing and experience atresia; dominant secondary follicle turns into the develop (Graafian) follicle; follicle frames a blister-like bulge because of the swelling antrum on the surface of the ovary

menstrual phase, events in the ovaries

FSH causes several primordial follicles form into primary follicles and afterwards into secondary follicles; may take several months to happen; follicle that starts to create toward the start of a specific menstrual cycle may not achieve maturity and ovulate until several menstrual cycles later

menstrual phase, events in the uterus

Flow from the uterus comprises of 50-150 mL of blood, tissue fluid, mucus, and epithelial cells shed from the endometrium; discharge happens on the grounds that the declining levels of progesterone and estrogens invigorate the arrival of prostaglandins that reason the uterine spiral arterioles to constrict; whole stratum useful is sloughed off; endometrium is thin; menstrual flow goes from the uterine cavity through the cervix and external genitals to the outside.
