  1. 1. Chapter 10 Reproductive System
  2. 2. Female Reproductive System <ul><li>Made up of 6 parts </li></ul><ul><ul><li>Breasts </li></ul></ul><ul><ul><li>Uterus </li></ul></ul><ul><ul><li>Fallopian Tubes </li></ul></ul><ul><ul><li>Ovaries </li></ul></ul><ul><ul><li>Vagina </li></ul></ul><ul><ul><li>Vulva </li></ul></ul>
  3. 3. Female Reproductive System <ul><li>Internal Genitalia </li></ul><ul><ul><li>Ovaries </li></ul></ul><ul><ul><ul><li>There are 2 ovaries, located one on each side of uterus </li></ul></ul></ul><ul><ul><ul><li>they are small, almond-shaped glands that produce ova and female sex hormones </li></ul></ul></ul><ul><ul><ul><ul><li>estrogen and progesterone </li></ul></ul></ul></ul><ul><ul><li>Fallopian Tubes </li></ul></ul><ul><ul><ul><li>also known as uterine tubes or oviducts </li></ul></ul></ul><ul><ul><ul><li>run from area around ovaries to either side of the upper portion of the uterus </li></ul></ul></ul><ul><ul><ul><li>at ovary end, they have finger-like projections called fimbriae to catch ovum after ovulation and direct it into the fallopian tube </li></ul></ul></ul>
  4. 4. Female Reproductive System <ul><li>Internal Genital (continued) </li></ul><ul><ul><li>Uterus </li></ul></ul><ul><ul><ul><li>a hollow, pear-shaped organ, located between bladder and rectum </li></ul></ul></ul><ul><ul><ul><li>made of 3 sections: </li></ul></ul></ul><ul><ul><ul><ul><li>fundus (upper portion): between where the fallopian tubes connect to the uterus </li></ul></ul></ul></ul><ul><ul><ul><ul><li>corpus (body): central portion </li></ul></ul></ul></ul><ul><ul><ul><ul><li>cervix (lower portion, Cx): neck of uterus, opens into the vagina </li></ul></ul></ul></ul><ul><ul><li>Vagina </li></ul></ul><ul><ul><ul><li>muscular tube that extends from cervix to outside of body </li></ul></ul></ul>
  5. 5. Female Reproductive System <ul><li>Vulva (External Genitalia) </li></ul><ul><ul><li>Labia Majora and Labia Minora </li></ul></ul><ul><ul><ul><li>folds of skin that protect genitalia, vaginal orifice and urinary meatus </li></ul></ul></ul><ul><ul><li>Clitoris </li></ul></ul><ul><ul><ul><li>small organ that contains sensitive erectile tissue </li></ul></ul></ul><ul><ul><li>Perineum </li></ul></ul><ul><ul><ul><li>region between vaginal orifice and anus </li></ul></ul></ul>
  6. 6. Female Reproductive System <ul><li>Breasts </li></ul><ul><ul><li>Contain mammary glands that produce milk in a process called lactation </li></ul></ul><ul><ul><ul><li>used to nourish a newborn </li></ul></ul></ul><ul><ul><ul><li>milk produced by lactiferous glands and carried to nipple by lactiferous ducts </li></ul></ul></ul>
  7. 7. Male Reproductive System <ul><li>Made up of 7 parts </li></ul><ul><ul><li>Testes </li></ul></ul><ul><ul><li>Epididymis </li></ul></ul><ul><ul><li>Vas Deferens </li></ul></ul><ul><ul><li>Seminal Vesicles </li></ul></ul><ul><ul><li>Prostate Gland </li></ul></ul><ul><ul><li>Bulbourethral Gland </li></ul></ul><ul><ul><li>Penis </li></ul></ul>
  8. 8. Male Reproductive System <ul><li>External Organs </li></ul><ul><ul><li>Testes (Testicles) </li></ul></ul><ul><ul><ul><li>oval shaped </li></ul></ul></ul><ul><ul><ul><li>responsible for production of sperm (spermatogenesis) </li></ul></ul></ul><ul><ul><ul><ul><li>occurs in seminiferous tubules </li></ul></ul></ul></ul><ul><ul><ul><li>suspended in scrotum outside of the body </li></ul></ul></ul><ul><ul><ul><li>production of testosterone occurs here as well </li></ul></ul></ul><ul><ul><li>Epididymis </li></ul></ul><ul><ul><ul><li>coiled tubule that lies on top of testes inside scrotum </li></ul></ul></ul><ul><ul><ul><li>location for sperm maturation and storage until released into vas deferens </li></ul></ul></ul>
  9. 9. Male Reproductive System <ul><li>External Organs (Continued) </li></ul><ul><ul><li>Penis </li></ul></ul><ul><ul><ul><li>contains erectile tissue </li></ul></ul></ul><ul><ul><ul><li>delivers sperm into female vagina </li></ul></ul></ul><ul><ul><ul><li>glans penis is the soft tip </li></ul></ul></ul><ul><ul><ul><li>prepuce is the protective covering </li></ul></ul></ul><ul><ul><ul><li>urinary meatus is the external opening in which the urethra extends from urinary bladder </li></ul></ul></ul>
  10. 10. Male Reproductive System <ul><li>Internal Organs </li></ul><ul><ul><li>Vas Deferens </li></ul></ul><ul><ul><ul><li>carries sperm from epididymis into pelvis cavity </li></ul></ul></ul><ul><ul><ul><li>travel in front of urinary bladder, over the top and down the back of bladder to empty into urethra </li></ul></ul></ul><ul><ul><ul><li>vas deferens, nerves, veins and lymphatic vessels form spermatic cord </li></ul></ul></ul><ul><ul><li>Seminal Vesicles (2) </li></ul></ul><ul><ul><ul><li>small glands located at base of urinary bladder </li></ul></ul></ul><ul><ul><ul><li>connected to vas deferens before it empties into urethra </li></ul></ul></ul><ul><ul><ul><li>secretes glucose-rich fluid to nourish sperm </li></ul></ul></ul>
  11. 11. Male Reproductive System <ul><li>Internal Organs (continued) </li></ul><ul><ul><li>Prostate Gland </li></ul></ul><ul><ul><ul><li>located below the urinary bladder </li></ul></ul></ul><ul><ul><ul><li>surrounds urethra </li></ul></ul></ul><ul><ul><ul><li>secretes an alkaline fluid to assist in keeping sperm alive by neutralizing pH of urethra and vagina </li></ul></ul></ul><ul><ul><li>Bulbourethral Glands </li></ul></ul><ul><ul><ul><li>also known as Cowper's Gland </li></ul></ul></ul><ul><ul><ul><li>consists of 2 small glands located on either side of urethra before the prostate </li></ul></ul></ul><ul><ul><ul><li>they produce a mucuslike lubricating fluir </li></ul></ul></ul>
