Lactates feed young: internal reproductive organs, ovaries (gonads, oviducts (= fallopian tubes, uterus (=womb, cervix, vagina, vulva, ovaries. Produces: gametes (oocytes) by process of oogenesis, sex hormones estradiol + progesterone, oviducts (=fallopian tubes) Cilia move 2degree oocyte (fertilized and unfertilized) down oviduct to uterus: uterus (=womb) Pear-shaped, about size of a fist expands greatly during pregnancy: myometrium thick wall composed of smooth muscle, endometrium consists of connective tissue, glands, and blood vessels. If no fertilization occurs endometrium sloughed off= menstruation: cervix lower portion of uterus. Closes uterus and separates it from the vagina. Human papillomavirus (hpv) responsible for 90% of cases of cervical cancer: vagina (=womb) Elastic muscular tube that extends to outside of body. Primary oocyte (2n)--> each is in a follicle: follicle components: Zona pellucida= thick layer of glycoproteins in between 1degree oocyte and follicle cells: oogenesis starting at puberty, secondary oocyte formation:
