Hormones In Everyday Life
With The Effects
By: Bria Martin & Jennecia Clark
Introduction
Have you ever met someone that can’t
control their hormones? Well the purpose
of this lab is to show how those hormones
can affect people physically and
emotionally.
Observations
The hormone test is developed by
stimulating protein production in muscle
cells and energy release from the
breakdown of fats. The HGH Level,
Human Growth Hormone Level, is tested A
blood sample can be drawn one to 1.5
hours after sleep or strenuous exercise
can be performed for 30 minutes before
blood is drawn.
Problem
How does the hormones in
the body affect the way the
person acts, does, and/or
feels?
Hypothesis
If someone feels one way,
then they’re going to act on
it as a human instinct.
Research
 Hormones are your body's chemical messengers. They
travel in your bloodstream to tissues or organs. They
work slowly, over time, and affect many different
processes, including
 Growth and development
 Metabolism - how your body gets energy from the
foods you eat
 Sexual function
 Reproduction
 Mood
Purpose
To find out how hormones
control your body.
Background Information
 Hormones are chemicals released by cells that affect cells in other parts of
the body. Only a small amount of hormone is required to alter cell
metabolism. It is essentially a chemical messenger that transports a signal
from one cell to another. All multicellular organisms produce hormones.
Hormones have the following effects on the body:
 Stimulation or inhibition of growth
 Mood swings
 Induction or suppression of apoptosis (programmed cell death)
 Activation or inhibition of the immune system
 Regulation of metabolism
 Preparation of the body for fighting, fleeing, mating, and other activity
 Preparation of the body for a new phase of life, such as puberty, caring for
offspring, and menopause
 Control of the reproductive cycle
 A hormone may also regulate the production and release of other
hormones. Hormone signals control the internal environment of the body
through homeostasis.
Materials
1 female
1 male
Hormone Tester
Procedure
 Usually for hormone testing, you have to
take blood and put it through a system to
read your functions.
1. Take blood 1.5 hours after sleep or 30
minutes after exercise.
2. Put strip of blood in hormone reader
3. Read your results.
Data
HYPOPHYSIS REGIONS
HORMONE
EFFECT
stimulates protein synthesis and growth
Growth Hormone: GH
PARS
DISTALIS
ACTH
stimulates the adrenal cortex to produce the glucocorticoids
TSH
stimulates the thyroid to produce and secrete thyroxin
in females, stimulates the development of follicles in the ovary and
FSH
their production of estrogen
in males, stimulates spermatogenesis
LH (ICSH)
in females, stimulates ovulation, the formation of the corpus
luteum and the production of progesterone by the corpus luteum
in males, stimulates the production of testosterone by the
interstitial cells
prolactin
PARS INTERMEDIA
PARS
NERVOSA
in females, stimulates the production of milk by mammary gland
MSH
no known effect
ADH
stimulates the kidneys to retain water
oxytocin
in females, stimulates contraction during parturition and milk
ejection by the mammary glands
Data (Continued)
HORMONE
EFFECT
controls the BMR (basal metabolic rate
thyroxin
cell respiration)
stimulates growth and development
stimulates deposition of calcium into bone
calcitonin
(by the osteoclasts)
Analysis
 There are many types of hormones, and the
effects that it could do to us. Hormones connect
to our nervous system which makes us react to
certain things. It may turn as in growth; help our
kidneys, and many other things. Hormones
mostly affect females. As you can see in the
chart, women have more effects than men and
in general. All in all, hormones help us, brighten
up our day, produce growth, etc. in our everyday
lives.
Conclusion
Hormones affect people in negative and
positive ways. People usually do
something on their instincts. Hormones
control the instinct sometimes. For
example, if you’re feeling angry, that’s your
hormone. Your instinct is to yell at
someone bothering you or to fight. Your
body is something that you can control
physically, not chemically.
