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 (Group Activities)

Harry Leaving HomeHarry 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 _______________.

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 SallyLooking 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!

Matching(Homework / Review)

• Contribute nutrients and fluid to semen

• Maturation and some storage of sperm

• Matured sperm are stored and propelled by muscle contractions

• Produces sperm and sex hormones

• Suspended within the scrotal sacs of the scrotum

Epididymides

Seminal vesicles

Testes

Seminiferous tubules

Urethra

Bulbourethral glands

Prostate Gland

Mature sperm•Provide mucous secretions with a lubricating effect

•Made of spongy erectile tissue containing blood spaces

•Contribute a milky alkaline fluid believed to activate or increase the mobility of sperm

•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 )
