  1. What two functions do both make and female reproductive organs have?
    Both have endocrine AND exocrine functions
  2. What is the endocrine function of the testes?
    • production of testosterone in the interstitial cells in the testicles
    • (interstitial cells are between the seminiferous tubules)
  3. What is the endocrine function of ovaries?
    production of estrogen (by the graafian follicles) & progesterone in the ovaries (and placenta) by the corpus luteum
  4. What is the exocrine function of the testicles?
    Sperm is produced in the seminiferous tubules

    semen=sperm + accessory gland seminal fluid
  5. Where is sperm produced and how long is it viable?
    • Sperm is produced in the testicles outside of the body
    • -this leads to a cooler temperature

    in 1 tsp of ejaculatory fluid there is ~400,000-500,000 sperm

    Sperm is viable for ~24-72 hours
  6. What is seminal fluid composed of and where it is produced?
    Seminal fluid is produced..

    1. Seminal vesicle: 70% of the fluid and sugar (fructose) for sperm energy

    2. Prostate gland: 20-30% of fluid and activation of sperm

    3. Cowper's or bulbourethral gland: alkaline cleansing of the urethra
  7. What is the spermatic cord?
    • Vas deferens
    • Veins/Artieries
    • Lymph bessels
    • Nerves
  8. What is the ejaculation pathway?
    seminiferous tubules-->epididymis-->vas deferens/spermatic cord-->common ejactuloatory duct-->prostatic, membranouse, and penile urethra
  9. What is the exocrine function of the ovaries?
    • Production of the oocyte
    • *also called egg/ovum, when fertilized becomes-->zygote-->embryo

    Secondary oocyte is produced by the Graafian Folicle
  10. Where does fertilization of the oocyte take place and how long is the oocyte viable?
    Fertilization of the secondary oocyte takes place 1/3 of the way into the fallopian tube (fimbria grabs the egg)

    Secondary oocyte is viable for 24 hours
  11. What are similarities between the penis and the clitoris?
    Both are anatomically similar

    female also has minor accessory glands
  12. How long does it take for the embry to implant in the uterine wall and to initiate placental growth?
    takes about 1-14 days

    placenta will take over hormone production until birth

    *the breast and the placenta are also considered reproductive organs
  13. What are the parts of a sperm?
    • -The acrosome (produces lysozyme to get into the egg)
    • -Head (contains DNA)
    • -Midpiece (contains mitochondria for ATP production)
    • -Tail (flagellum)
  14. Name this structure
    Graafian Follicle with secondary oocyte
  15. name this structure
    seminiferous tubule producing sperm
  16. Name this Structure
    Sperm
  17. In fetal ciruclation, where is O2 high, where is it mixed, and where is it low?
    Umbilical vein and ductus verosus- High O2

    After the blood leaves the ductus verosus, it becomes mixed and remains mixed until the umbilical arteries

    umbilical arteries: low O2 (goes to placenta)
  18. What is the purpose of the umbilical arterty and what does it become after birth?
    The umbilical artery brings blood to the placenta for removal

    After birth, it becomes the uterine vessels and ligaments
  19. What is the purpose of the umbilical vein and what does it become after birth?
    it brings O2 rich blood to the fetus

    after birth it becomes the ligamentum teres
  20. What is the purpose of the Ductus venosus and what does it become after birth?
    The ductus venosus is high in O2 and bypasses the liver

    after birth, it becomes the ligamentum arteriosum
  21. What is the purpose of the Ductus Arteriosus and what does it become after birth?
    The Ductus Arteriosus shunts blood away from the lungs by sending it from the PAT to the Aorta

    After birth, it becomes the ligametum arteriosum
  22. What is the purpose of the Foramen Ovale and what does it become after birth?
    the forman ovale shunts blood from the lungs by taking it from the right atrium to the left atrium

    after birth, it becomes the fossa ovalis
  23. What organ serves as the respiratory/digestive/and excretory organ for the fetus?
    the placenta
