  1. Sally Harry How can Harry find Sally? Mark Harry’s path in the following slides.

  2. Where was Harry born and how does he travel?

  3. How can Harry find Sally?

  4. Male Reproductive System

  5. Male Reproductive System 1. Testes (2) • Ascend/Descend • Produce sperm and sex hormones • Seminiferous tubules (250 m) 2. Epididymides (2) • Maturation and some storage of sperm

  6. 3. Vas Deferens (2) • Some storage of matured sperm and propulsion by muscle contractions 4. Seminal Vesicles (2) • Gland • Join vas deferens • Nutrients

  7. 5. Prostate Gland • Milky alkaline solution (Basic - OH) – neutralization and mobility 6. Bulbourethral Glands (2) • Mucus secretion – lubricating effect

  8. 7. Urethra • Carries semen • Carries urine • Opens to the outside environment

  9. Harry the Sperm*Harry Leaving Home

  10. Harry Leaving Home As time went by, Harry and his siblings matured and were ready to leave their home in the _______________. One day, they were propelled through a tube called _______________ to look for Sally. Along the way, they were joined by materials delivered by three other glands to help them on their journey. The first gland was the _______________ which delivered nutrients to Harry and his siblings. The second gland, known as the _______________, delivered a milky alkaline fluid so Harry and the crowd could begin to swim. The third one, named the _______________, delivered a mucus secretion. The mixture, including Harry and his siblings, is called _______________. With all the materials needed for the journey, Harry traveled through the _______________ into another tube called the _______________. This tube is surrounded by erectile tissue and is used by both the Urinary System and the _______________. However, only urine or _______________ can pass through the _______________ at a time. When the spongy erectile tissue is filled with blood, a valve blocks off the branch to the bladder so Harry and his siblings can be released from the _______________. reproductive system seminal vesicles egg scrotal sac semen cervix prostate gland scrotum uterus sperm(s) bulbourethral glands epididymis vagina seminiferous tubules urethra penis fallopian tube(s) testicles vas deferens ovary epididymis vas deferens seminal vesicles prostate gland bulbourethra gland semen vas deferens urethra reproductive system semen urethra penis

  11. Drag and Drop Activity(Individual Activity)

  12. Female Reproductive System

  13. Female Reproductive System 1. Ovaries (2) • Produce egg and sex hormones • Follicles 2. Fallopian Tubes (2) • Oviducts • Tubular fertilization

  14. 3. Uterus • Endometrium (inside lining) 4. Cervix • Pap smear • Hysterectomy

  15. 5. Vagina • Muscular tube • Produces substances that are metabolized into acids • Opens to the outside environment

  16. Looking for Sally (Individual Activity)

  17. Looking for Sally Once released, Harry swam into the ____________. The alkaline fluid from the ____________ helps neutralize the acidic environment of the ____________ long enough so that Harry and his siblings can swim through the ____________, into the ____________, and find the entrance into one of the ____________. Harry swam as fast as he could because that is the place he might have a chance to meet Sally. This will only be possible if Sally the ____________ (female reproductive cell) is released from the ____________, made/makes her way into the ____________, and can be found and fertilized by a ____________. Then the fertilized ____________ will continue down the ____________ and embed herself in the ____________ lining of the ____________. If Harry can not find or fertilize Sally in the ____________, Sally will continue down the ____________ and into the ____________, exit through the ____________, and out the ____________. In that case, the ____________ lining is not needed, and it will be released through the ____________ during menstruation. Let’s wish Harry and Sally good luck! reproductive system seminal vesicles egg scrotal sac semen cervix prostate gland scrotum uterus sperm(s) bulbourethral glands epididymis vagina seminiferous tubules urethra penis fallopian tube(s) testicles vas deferens ovary vagina vagina prostate gland cervix uterus fallopian tubes egg ovary fallopian tubes fallopian tubes sperm egg endometrium uterus fallopian tubes fallopian tubes uterus cervix vagina endometrium vagina

  18. External Genitals • Vulva- collectively • Mons Pubis- fatty tissue • Labia Majora- extend backward • Labia Minora- extend forward • Clitoris- organ homologous to the penis

  19. Labeling (Individual Activity)

  20. Fallopian tube (oviduct) Ovary Uterus Cervix Urinary bladder Rectum Urethra Vagina Clitoris Labium minora Anus Labium majora Vagina orifice Label the female reproductive system

  21. Tracing Activity(Individual Activity)

  22. Where was Harry born and how does he travel?

  23. How can Harry find Sally?

  24. Matching(Homework / Review)

  25. Contribute nutrients and fluid to semen Testes • Maturation and some storage of sperm Seminiferous tubules • Matured sperm are stored and propelled by muscle contractions Epididymides • Produces sperm and sex hormones Vasa Deferentia • Suspended within the scrotal sacs of the scrotum Seminal vesicles

  26. Made up of a head with a nucleus and acrosome, a middle with a high concentration of mitochondria, and a flagella Prostate Gland • Used for both the urinary and reproductive systems in male (but only urinary systems in female ) Bulbourethral glands • Made of spongy erectile tissue containing blood spaces Urethra • Contribute a milky alkaline fluid believed to activate or increase the mobility of sperm Penis • Provide mucous secretions with a lubricating effect Mature sperm

  27. Concluding Remarks

  28. A Simple Equation:Tablets + Interactive Design = Better Biology Learning
