Lab 29

Reproductive System

QuestionAnswer
Uterine tubes/ Oviducts Transport oocyte from ovary to uterus; site of fertilization
Urinary bladder Stores urine prior to excretion
Uterus Where embryo implants & fetal develops
Vagina Canal connect to uterus’ exterior
Cervix Connect uterus to vagina; produce mucus & block sperm
Ovary Produce oocytes (eggs) secret estrogen & progesterone
Prostate produce alkaline fluid with semen; help activate sperm & neutralize activity
Urethra conduct urine & semen separately; passes through the penis
Penis delivers semen
Testis produce sperm & secretes testosterone
Vas deferens transport sperm from epididymis to ejaculatory duct
Seminal vesicles produce nutrient-rich fluid (mainly fructose) contributing majority of semen volume
Epididymis where sperm maturate
Follicular Phase Oocyte develops inside follicle Follicles mature; estrogen levels increase to stimulate the thickening of the uterine lining (endometrium) Oogenesis: production of female gametes Folliculogensis: growth & development of ovarian follicles
Luteal Phase Formation of corpus luteum (‘yellowish body’); secretes progesterone, inhibiting GnRH production & increased FSH & LH (to start the cycle again); supports possible pregnancy; post-ovulation
Ovulation Phase Rupture follicle triggered by LH surge; release of oocyte from ovary; Occurs around day 14 (typical cycle); between luteal and follicular phase
Secretory Phase Endometrium thickens and becomes glandular; corpus luteum produce progesterone; progesterone prepares uterus for implantation
Menses Phase Shedding of uterine lining (woman menstruates) Occurs when hormone levels drop w/o pregnancy
Lumen of testes central space where sperm are released
Spermatogenic cells cells that develop into sperm
Seminiferous tubules site of sperm production
Interstitial cells produce testosterone
Follicles contain developing oocytes; different stages indicate ovarian cycle progression
seminiferous tubules produce sperm; located in testes
Sperm pathway Seminiferous tubules -> epididymis -> vas deferens -> ejaculatory duct -> urethra
How are the ovarian and uterine cycle related? They occur simultaneously Controlled by the same hormones Ovarian hormones regulate uterine changes
