1. Male / female anatomy

2. Warm-up What is puberty?
List 5 changes that occur to the male and 5 changes that occur to the female.
What system of the body is responsible for the changes that occur during puberty?

3. Puberty - A series of events by which a child becomes
A young adult. Characterized by secretions of hormones,
Development of secondary sex characteristics,
Reproductive functions, and growth spurts
Changes during puberty
Female
Develop breasts
Hips widen
Pubic, underarm and leg hair
Thicken and darken
Period
Changes during puberty
Males
Voice changes / deepens
Pubic underarm or
Facial hair
Growth Spurts
Acne
What system is responsible?
The endocrine system, the foundation of the endocrine
System is the series of glands and hormones they produce.
Hormones are the bodies chemical messenger.

4. Male anatomy

5. Bladder
Organ responsible for holding liquid waste products.

6. Pubic bone & Pubis One of 3 sections of the hip bone
Form the front of the pelvis
The mons pubis, or the pubis is the soft
Mound fat just under the flesh (present
in both genders) used to protect the pubic
bone

7. Vas deferens / Ductus
A long thin duct extending up from each epididymis to the urethra in the penis
Each tube is 18 inches long and has hair like projections called cillia that help move sperm along.

8. Penis
May appear to be one cylinder. The penis consists of three tubes that contain the sponge-like tissue necessary for an erection.

9. Urethra
Serves as the passage way from the bladder through the prostate gland where it joins the ejaculatory duct and runs all the way down through the opening of the penis.
Carries both urine and sperm, but never at the same time.

10. Foreskin A fold of skin covering the head of the penis
Some boys have the foreskin removed shortly after birth through a surgical procedure called circumcision

11. scrotum Sac like structure that holds the testes
Regulates the temperature of the testes
In order for sperm to be produced the temperature of the testes must be a few degrees lower than normal body temperature

12. Testes 2 of them Also known as the testicles
Produce sperm and the male hormone testosterone

13. Epididymis One rests on the top of each testes
The coiled tube measures 20 feet long in a grown man
Stores sperm and allows them to mature.
Sperm leaves the epididymis and enters the vas deferens.

14. Seminal vesicle Adjoins the vas deferens by means of a duct
During ejaculation the seminal vesicle adds fluid called seminal fluid, to the sperm for passage through the urethra.
Known as semen

15. Prostate gland
A small muscular gland that produces a fluid that prolongs sperm life.
Helps to neutralize the acid environment of the vagina. Sperm unprotected by this fluid would die in an acid environment.
This fluid makes up the greatest part of the semen

16. Cowper’s gland / Bulbourethral gland
This tiny gland secretes a small amount of fluid that neutralizes the acid in the males urethra.
When a male is sexually aroused, tiny clear drops of this secretion (pre-ejaculatory fluid) can appear at the tip of the penis.
Pregnancy can result even if no ejaculation occurs

17. Ejaculatory Duct These ducts (each male has
2 of them) causes the reflex
Of ejaculation
During Ejaculation
semen passes Through
the ducts and exits the
body Through the penis

18. Corpus Spongiosum Glans Penis Corpora Cavernosa
Mass of spongy tissue that surrounds the urethra
Glans Penis
Sensitive erectile tip of the penis, found below the foreskin
Corpora Cavernosa
Means “cave like” it is a large amount of spongy tissue
That holds the majority of blood during an erection
Who knew guys were that
Complicated!

19. Female anatomy

20. Fallopian Tubes / Uterine Tubes
Branch out from either side of the body of the uterus and forms the passages through which the egg is transported from the ovary into the uterus

21. Ovary Females have 2 ovaries They produce eggs
Produce estrogen and progesterone

22. Bladder
Organ responsible for holding liquid waste products

23. Pubic bone / Pubis One of 3 sections of the hip bone
Form the front of the pelvis
The mons pubis, or the pubis is the soft
Mound fat just under the flesh (present
in both genders) used to protect the pubic
bone

24. Urethra
A passageway leading from the bladder discharging urine externally

25. Clitoris Similar in sexual response as the penis.
A tiny organ at the top of the labia minora containing many nerve endings, making it sensitive to sexual stimuli

26. Labia / Labium LABIA MINORA
The small and innermost set of vaginal lips, forms a small hood at the top to cover the clitoris
LABIA MAJORA
large and outer most set of vaginal lips

27. Vagina
Birth canal
A tube extending from the cervix of the uterus to the outer female sexual organs.
Serves as a passageway for (1) menstrual flow (2) sperm during sexual intercourse (3) the baby during birth

28. Fimbriea
Finger-like processes located at the opening of the Fallopian tube.
Be sure to add these onto your color sheets

29. Uterus
A hollow structure with a muscular lining that has a shape somewhat like that of an upside-down pear.
Two inches wide across the top and one inch wide across the bottom and three inches in length
Also called the Womb
Broken into the body and cervix

30. Cervix The neck of the uterus.
The cervix is located at the narrow part of the uterus.
Keeps the baby in the uterus while it grows
During the birth process, the cervix opens up (or dilates) to let the baby out

31. Ovulation / Menstrual Cycle
Menstrual Cycle - sequence of events in the
Reproductive System that occurs,
preparing itself for pregnancy
Length - 28 days, but will vary.
Day new ova is maturing inside ovary.
Day 14 Ovulation - release of a mature egg
from one or The other ovaries into the
fallopian tube If the egg is not fertilized
within hours after it is released from
The ovaries, it begins to break down, can
no longer be fertilized

32. Cont... Day 21 - ova enters the uterus
Day Uterus thickens in preparation to receive ova
And begin nourishing fertilized egg. Blood vessels grow into
Thick lining (endometrium) Egg travels into fallopian tube
Day 21 - ova enters the uterus
Day 28 - if egg has not been fertilized menstruation occurs.
Lining becomes unattached, mixture of blood and cells, lasts
5-7 days
