Title: MATURATION
1- --------
- MATURATION
- --------
2To MATURE
- Means to become fully grown or developed
- Right now you are maturing in many ways
- Your endocrine reproductive systems help you to
mature - Changes occur in your body in how you think
feel
3The Endocrine System
- Consists of glands that produce hormones
- Is the chemical communication system that
controls many body functions. -
4- Hormone- Chemical messenger in bloodstream that
controls many body activities are secreted by
glands -
5- Gland- Group of cells or organ that secretes a
substance - Pituitary
- Thyroid
- Parathyroid
- Adrenal
- Pineal Body
- Reproductive
-
6The Pituitary Gland
- -At base of brain
- Pea-sized
- Master Gland
- Coordinates the endocrine nervous systems
- Stimulates other endocrine glands to release
their hormones
7The Ovaries
- Female reproductive glands
- Produce egg cells estrogen
- Estrogen- Female sex hormone that controls the
development of secondary sex characteristics
during puberty
8The Testes
- 2 male reproductive glands
- Produce sperm cells testosterone
- Testosterone- Male sex hormone that controls the
development of secondary sex characteristics
9Puberty
- Stage where secondary sex characteristics appear
- Females- 8-15
- Males- 12-15
10Adolescence
A simple definition is the time of life between
childhood adulthood.
11SECONDARY SEX CHARACTERISTICS THAT OCCUR DURING
PUBERTY ---------------------------------- MALES
-Deepening of voice -Growth of facial
hair -Growth of underarm hair -Muscle
Growth -Growth of pubic hair -Start of sperm
development -Increase in ht. of 4-12
12SECONDARY SEX CHARACTERISTICS THAT OCCUR DURING
PUBERTY ---------------------------------- FEMALE
S -Widening of hips -Breast development -Growth
of underarm hair -Growth of pubic hair -Start of
menstruation -Formation of mature eggs -Increase
in ht. of 2-8
13HOMEOSTASISA state of chemical balance
regularity in our bodies
14During puberty
- You may experience slight mood changes during
puberty due to hormone level changes
- If the changes occurring in your body bother you,
discuss them with a parent or doctor
15Problems of the Endocrine System Extra Credit
- Underactive / Overactive Thyroid
- Dwarfism
- Type 2 Diabetes
- Gigantism
- Type 1 Diabetes
- Hypogonadism
- Gynecomastia
-1-2 Pages -Write or type -Cite your source(s)
16Reproductive System
- Are the body systems that consist of the body
organs that produce offspring
17Female Reproductive System
Ovaries Fallopian Tubes Uterus Endometrium Ce
rvix Vagina
18Ovaries
- Produce egg cells estrogen
- Egg cells are female reproductive cells
- Females are born w/ up to 250,000 immature egg
cells!!! - About 400 of these will mature in their
lifetimes. - Each egg is enclosed in a follicle
19Ovaries
- During puberty, egg cells begin to develop
- OVULATION 1 egg is released from its follicle
each month by the ovaries
20- Uterus- Shelters supports the fetus during
pregnancy
- Cervix Opening of the uterus
21- Fallopian Tube- 4 tube that carries eggs from
the ovaries to the uterus
22 - The lining of the uterus begins to thicken as
this happens in preparation for the possible
beginning of a new life.
23FEMALE REPRODUCTIVE ANATOMY
Muscular passageway from the uterus to the
outside of the body
The lining of the uterus
24What happens when eggs are released by the
ovaries? One of two things 1) It is not
fertilized is released by the body through
menstruation 2) It is fertilized pregnancy
occurs
25- When the egg is released from an ovary not
fertilized, it leaves the body during menstrual
flow. - Menstrual Cycle- Series of monthly changes that
occur in the female reproductive system. - Eggs will be fertilized in the Fallopian tube or
released to the uterus

27(No Transcript)
28- Conception / Fertilization
- If sperm are present when an egg is moving
through a fallopian tube, a sperm may penetrate
the egg
29- Question
- Can more than 1 sperm cell fertilize a single
egg?
30Male Reproductive System
- Penis -Vas Deferens
- Testicles -Epididymis
- Seminal Vesicles -Scrotum
- Prostate Gland -Utethra
- Cowpers Glands
31PRODUCE SPERM
32STORE SPERM
33Provide nutrients For semen-up to 60 of total
composition
34Controls the release of urine from the bladder
secretes a fluid that helps sperm cells to
survive.
35Muscular tubes that help propel semen from body
36Carries urine from the kidneys to the bladder
37Protects testes regulates temperature
38URETHRA- Tube that carries urine semen out of
the body
39Sperm Cells
- Male reproductive cells
- A healthy male produces about 500,000,000 sperm
per day - 1 sperm cell - .05 mm in length
- A sperm cell takes 10 weeks to mature
- Each testis produces about 1,500 sperm cells per
second - They swim at a rate of 3 mm per hour
40When a male is sexually stimulated, sperm leave
the testes through tubes that lead to the
urethra.Along the way they mix w/ fluids that
protect them help them to travelSemen-
mixture of sperm cells fluids that protect them
help them to move
41Care of the Male Reproductive System
- -At birth, the end of the penis is covered by a
loosely fitting skin called foreskin - -Circumcision- Removal of this skin
- -May reduce chances of urinary infections
-If not circumcised, males should pull foreskin
back to clearn regularly
42Care of the Male Reproductive System
- 1- Choose abstinence
- 2- Have Regular medical checkups
- 3- Wear athletic supporter / equipment in sports
- 4- Bathe or shower daily
- 5- Testicular examinations
43Care of the Female Reproductive System
- 1- Choose abstinence
- 2- Have Regular medical checkups
- 3- Keep track of menstrual periods to allow
doctors to know if they are regular
- 4- Regular exercise caffeine reduction can
reduce cramping - 5- Regular breast self-examinations
- 6- Practice good health habits during
menstruation -
44Wrap-Up
- Speak to a trusted adult if you have concerns
about your changes or appearance
- -It is helpful to feel good about your changing
body during puberty - Body Image- Perception you have about your bodys
appearance
