DO AN ICE JOB!
1. What initially happens when the ice
touches your skin?
2. What happens after more time
passes?
3. What happens when the ice is
removed?
4. How do you think Jack Thayer
managed to survive after the sinking
of the Titanic?
HOMEOSTASIS
The human
body’s
maintenance
of a stable
internal
environment.
My
Beloved
Cells
I will miss
you!
If
homeostasis
is interrupted,
cells suffer
and
sometimes
die.
THE WORK OF CELLS
On a baseball team,
every player has his job.
Cells have their own
positions (or jobs) in
the body!
RED BLOOD CELLS
Groups of cells working
together form a TISSUE
There are 4 types of tissues:
•
•
•
•
Epithelial Tissue
Nervous Tissue
Muscle Tissue
Connective Tissue
EPITHELIAL TISSUE
Covers and protects underlying tissue.
When you look at the surface of your
skin, you see epithelial tissue
NERVOUS TISSUE
Sends electrical signals through the
body. It is found in the brain,
nerves and sense organs.
MUSCLE TISSUE
Made up of cells that can contract
and relax to produce movement
CONNECTIVE TISSUE
Joins, supports, protects, insulates,
nourishes, and cushions organs. It
also keeps organs from falling apart.
TISSUE + TISSUE= ORGAN
Two or more tissues working together,
form an organ.
One type of
tissue alone
cannot do all
of the things
that several
types working
together can
do.
ORGAN + ORGAN = ORGAN SYSTEM
Organs working together
make up an organ system.
The failure of any
part can affect
the entire system
11 MAJOR ORGAN SYSTEMS
• Integumentary system
• Reproductive system.
• Muscular system
• Nervous system
• Skeletal system
• Cardiovascular system
• Respiratory system
• Urinary system
• Lymphatic system
• Digestive system
• Endocrine system
Integumentary System
Includes
skin, hair,
nails and
their
underlying
tissues
Muscular System
Skeletal muscles move bones.
Skeletal System
Bones frame
and protect
body parts.
Cardiovascular
System
The heart
pumps
blood
through
blood
vessels.
Respiratory System
Lungs absorb oxygen and
release carbon dioxide.
Urinary System
Removes wastes from the blood and
regulates body fluids.
Reproductive System
Females produces eggs, feed/shelter
unborn baby- males produce sperm.
Nervous System
Receives and sends electrical
messages.
Lymphatic
System
Returns leaked
fluids to blood
vessels and
helps flush
harmful germs
out.
Digestive System
Breaks
down
food into
nutrients
.
Endocrine System
Glands regulate body functions by
sending out chemical messages.

DISCUSSION QUESTIONS
1. Explain the relationship between cells,
tissues, organs and organ systems.
2. Compare the four kinds of tissues found in
the human body.
3. Describe a time when homeostasis was
disrupted in your body.
Which body systems do
you think were effected?
T/F QUICK QUIZ
1. Homeostasis is the maintenance of a
stable internal environment.
2. Epithelial tissue sends electrical signals
throughout the body.
3. Blood is a type of connective tissue.
4. The endocrine system consists of skin,
hair, nails and their underlying
tissue.
5. The lymphatic system returns
leaked fluids to blood vessels.
