Presentation Transcript

Slide1

Reproductive AnatomySlide2

Social:

Medical:

“doing it”

“sex” or “sexual intercourse”

“her time of the month”

“period”

“boobs”

“breasts”

“balls”

“testicles”

The difference: There’s nothing inappropriate about the social level,

but I prefer the class to attempt to learn and use the medical terms.Slide3

WHAT IS PUBERTY

the period during which adolescents reach sexual maturity and become capable of reproduction.Slide4

General Terms

1.

Adolescence: A bridge between childhood and adulthood. Puberty lasts several years and occurs during the early teens.2. Puberty: The time when a person reaches sexual maturity.3. Hormones: Chemicals made in the body that cause change and growth.4. Intercourse: The sexual act of placing the penis into the vagina in order to deposit sperm for conceptionSlide5

PHYSICAL CHANGES DURING PUBERTY

Female

Development of breastsMenstruation beginsWidening of hipsMaleGrowth of genitals (testicles and penis)Production of spermEjaculation becomes possibleBroadening of shouldersDeepening of voiceSlide6

PHYSICAL CHANGES IN BOTH

Acne

Reproduction becomes possibleGrowth spurt (height and weight)Reproduction hormones become more activeIncreased hair growthChange in underarm smell, perspiration and hair growth.Slide7

When does puberty occur?

There is no set age or time for puberty to occur

Teens go through puberty at all different timesNo need to worry if you haven’t experienced the changes yet!Typical range:Boys: 11-14Girls: 9-13Slide8

Before puberty, the testosterone level in boys is normally low.

Testosterone increases during puberty.

This causes boys to develop a deeper voice, get bigger muscles, and get facial and body hair. Copyright © 2010 Ryan P. MurphySlide9

Sexual Health

When does sexual health begin?

BIRTH!Development of sex organsHormonesGrowth/developmentRelationships develop throughout lifeSlide25

Sex Cells

Female:

Ovum (egg) released from the ovaryMale:Sperm released from the testesSlide26

Fertilization: when a sperm and egg join to make the first cells of a new babySlide27

Does sexual maturity mean you are mature enough for sex?

Sexual maturity

physicalfemales are capable of conceiving a baby and carrying for 9 monthsmales are capable of getting a female pregnantMature enough for sexemotionalare you capable of dealing with the consequences?are you willing to abandon your values on the subject?are you prepared for the stress that comes with a sexual relationship?Slide28

Activity!

Label the changes during puberty (differences and similarities) experienced by boys and girls.

The reproductive system is not needed to keep you alive like all of the other systems.

It is responsible for keeping the species from going extinct.

Copyright © 2010 Ryan P. MurphySlide30

The Reproductive System: Produces, stores, nourishes, and releases sex cells.

Copyright © 2010 Ryan P. MurphySlide31

Sperm: Male sex cell (gamete)

SpermSlide32

Egg (Ovum): Female sex cell.

EggSlide33

Fertilization: The joining of the egg and the sperm.

The sperm and egg contain genetic information that will allow this one cell to multiply into trillions.

Female Anatomy: External

The external organs are contained in an area called the

Vulva:Outer labiaInner labiaHymenOpening to the vaginaClitorisSlide35

Female Anatomy: Internal

Vagina

:Stretchable passage between the vulva, cervix, and uterusAbout 4 to 5 inches in lengthAlso known as the: birth canal organ of intercourseSlide36

Female Anatomy: Internal

Cervix

:Opening to the uterusThe cervix plays a very important role in reproduction. Without a “strong” cervix, a female would not be able to naturally hold a fetusUterus:Also known as the wombLined by a thick blood filled blanket called the endometriumThe uterus is a very strong muscular organ. The function is to house and support the developing fetusSlide37

Female Anatomy: Internal

Endometrium

:Develops throughout the menstrual cycleShed if fertilization and implantation do not occur. This is called menstruationFallopian Tubes:Extend from the top of each side of the uterus each tube ends near an ovaryOuter edge of the tubes has fimbria that sweep the mature eggs from the ovary into the tubeSlide38

Female Anatomy: Internal

Ovaries

:Attached by ligaments to each side of the uterus and to the walls of the pelvisEach ovary has thousands of folliclesEach follicle has an immature eggEgg (Ovum):Female reproductive cellThe largest human cell (about the side of a grain of salt)Slide39

With your group, read the paragraph and fill in the blanks.Slide42

Male Anatomy

Penis

:Formed of spongy tissue that fills with blood and becomes erect during sexual excitementEjaculation:Occurs from the penisNot all erections end in ejaculations!Slide43

Male Anatomy

Glan

:Soft top of the penis foreskin covers the glans in uncircumcised men.Foreskin:Retractable tube of skin that covers and protects the glans of the penisCircumcision removes the foreskinSlide44

Male Anatomy

Scrotum:

Sac of skin which holds the testes, Epididymides and vas deferensKeeps testes up to 5 degrees cooler than normal body temperature; to allow for sperm productionAlso protects testes from injury to some degreeSlide45

Male Anatomy

Testes:

Two ball like glandsProduce spermProduce testosteroneUrethra:Tube that runs from the bladder to the opening in the glans of the penisCarriers urine from the bladder and semen from the vas deferensSlide46

Male Anatomy

Epididymis:

Each is a tube tightly coiled over the top and behind each testesWhere the sperm maturesVas Deferens:Two long narrow tubes that carry the sperm from each epididymis to the seminal vesiclesSlide47

Male Anatomy

Prostate Gland:

Located below the bladderProduces a thin fluid to help sperm moveFertilizes spermCowpers Gland:Secrete fluids that male the seminal fluid stickySlide48

Male Anatomy

Seminal Vesicle:

Located beneath the bladderProduce seminal fluid in which sperm move and are nourishedThis fluid, along with secretions from the Prostate Gland and Cowper’s Gland is called semenSemen:Thick white fluid containing spermatozoa that is ejaculated by the male genital tract.Semen does not consist of only spermSlide49

Flip Over The Page!

With your group, read the paragraph and fill in the blanks. Slide50

Activity!

Put the path of the sperm and the path of the egg in order of how they pass through the reproductive system. Slide51

Exit Ticket

Question: What is the path traveled by a sperm cell?

Journal:Was most of this new information to you or had you learnedit before?Slide52

Activity: vocab matching

With a partner, attempt to match the vocabulary with it's description
