How can Harry find Sally? Mark Harrys path in the following slides. Sally Harry Where was Harry born and how does he travel? How can Harry find Sally? Male Reproductive System 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

3. Vas Deferens (2) Some storage of matured sperm and propulsion by muscle contractions 4. Seminal Vesicles (2) Gland

Join vas deferens Nutrients 5. Prostate Gland Milky alkaline solution (Basic - OH) neutralization and mobility 6. Bulbourethral Glands (2) Mucus secretion lubricating effect

7. Urethra Carries semen Carries urine Opens to the outside environment Harry the Sperm * Harry Leaving Home Harry Leaving Home reproductive system

As time went by, Harry and his siblings matured and were ready to epididymis leave their home in the _______________. One day, they were propelled through vas deferens 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 seminal vesicles seminal vesicles egg scrotal sac

semen cervix prostate gland first gland was the _______________ which delivered nutrients to Harry and his prostate gland siblings. The second gland, known as the _______________, delivered a milky scrotum uterus sperm(s) alkaline fluid so Harry and the crowd could begin to swim. The third one, named

bulbourethra gland the _______________, delivered a mucus secretion. The mixture, including semen epididymis vagina Harry and his siblings, is called _______________. With all the materials needed vas deferens for the journey, Harry traveled through the _______________ into another tube urethra

called the _______________. This tube is surrounded by erectile tissue and is reproductive system used by both the Urinary System and the _______________. However, only urine semen bulbourethral glands urethra 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 penis

bladder so Harry and his siblings can be released from the _______________. seminiferous tubules urethra penis fallopian tube(s) testicles vas deferens ovary Drag and Drop Activity (Individual Activity)

Female Reproductive System Female Reproductive System 1. Ovaries (2) Produce egg and sex hormones Follicles 2. Fallopian Tubes (2)

Oviducts Tubular fertilization 3. Uterus Endometrium (inside lining) 4. Cervix Pap smear Hysterectomy

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

Looking for Sally (Individual Activity) Looking for Sally reproductive system vagina Once released, Harry swam into the ____________. The alkaline fluid from the vagina prostate gland

____________ helps neutralize the acidic environment of the ____________ long enough cervix uterus so that Harry and his siblings can swim through the ____________, into the ____________, fallopian tubes seminal vesicles egg scrotal sac semen cervix

prostate gland and find the entrance into one of the ____________. Harry swam as fast as he could scrotum because that is the place he might have a chance to meet Sally. This will only be possible egg ovary if Sally the ____________ (female reproductive cell) is released from the ____________, fallopian tubes

made/makes her way into the ____________, and can be found and fertilized by a sperm egg fallopian tubes ____________. Then the fertilized ____________ will continue down the ____________ and endometrium embed herself in the ____________ lining of the ____________. uterus

cervix down the ____________ and into the ____________, exit through the ____________, and vagina endometrium out the ____________. In that case, the ____________ lining is not needed, and it will be released through the ____________ during menstruation. Lets wish Harry and Sally good luck! vagina bulbourethral glands

epididymis vagina seminiferous tubules penis If Harry can not find or fertilize Sally in the ____________, Sally will continue uterus sperm(s) urethra fallopian tubes fallopian tubes

Tracing Activity (Individual Activity) Where was Harry born and how does he travel? How can Harry find Sally? Matching (Homework / Review) Testes Seminiferous tubules

Epididymides Contribute nutrients and fluid to semen Maturation and some storage of sperm Matured sperm are stored and propelled by muscle contractions Vasa Deferentia

Produces sperm and sex hormones Seminal vesicles Suspended within the scrotal sacs of the scrotum Prostate Gland Bulbourethral glands

Made up of a head with a nucleus and acrosome, a middle with a high concentration of mitochondria, and a flagella Used for both the urinary and reproductive systems in male (but only urinary systems in female ) Urethra Made of spongy erectile

tissue containing blood spaces Penis Contribute a milky alkaline fluid believed to activate or increase the mobility of sperm Mature sperm Provide mucous secretions with a

lubricating effect Concluding Remarks A Simple Equation: Tablets + Interactive Design = Better Biology Learning
