LEVELS OF ORGANIZATION
• WHAT DO YOU THINK THE 5 LEVELS OF
ORGANIZATION ARE IN THE BODY??
• BRAINSTORM WITH YOUR GROUP AND WRITE
DOWN WHAT YOU THINK ARE THE 5 LEVELS –
OLDEST PERSON WILL BE THE RECORDER. YOU
HAVE 5 MINUTES.
LEVELS OF ORGANIZATION:
THE ARRANGEMENT OF
SPECIALIZED PARTS WITHIN A
LIVING THING.
THE LABOR (WORK) IS DIVIDED
AMONG 5 DIFFERENT LEVELS.
WHAT IS DIVISION OF LABOR??
DIVISION OF LABOR
Within multi-cellular organisms there is
Division of labor.
Division of labor - the work (labor) of keeping
the organism alive is divided (division) among
the different parts of the body.
Each part has a job to do and as each part does
its special job, it works in harmony with all the
other parts.
1ST LEVEL - CELLS
• CELLS ARE THE BASIC
UNIT OF LIVING
THINGS.
• THEY ARE VERY
DIVERSE AND ALL
PARTS OF THE CELL
PERFORM SPECIFIC
FUNCTIONS.
Plant Cell
Animal Cell
CELLS: LOTS OF DIFFERENT KINDS!
HERE ARE TWO EXAMPLES. CAN YOU GUESS WHAT
KIND?
Nerve Cells
Skin Cells
SECOND LEVEL: TISSUES
In any multi-cellular organism, cells rarely work alone.
Tissues are the second level
Tissues are Cells that are similar in structure and function
and are usually joined together to form tissues.
There are four basic/major types of tissues in the human
body: Muscle tissue, nerve tissue, connective tissue, and
epithelial tissue. (There are other kinds of tissues besides these.) Other
kinds of tissue include bone tissue (a strong solid tissue that gives you shape
and support) made of bone cells in your body form bone tissue. Blood cells in
your body are part of blood tissue, a liquid tissue responsible for transporting
food and oxygen throughout the body.
LET’S LOOK AGAIN…
Here are the cells we saw before, but if you look closely, you can
see that they all look similar. Nerve cells working together make
nerve tissue, and skin cells make up a special type of epithelial
tissue.
TAKEN ONE AT A TIME….
Connective tissue
connects and supports
parts of the body.
Blood, fat, ligaments,
cartilage, bones, and
tendons are all
connective tissues.
Epithelial tissue covers and
lines the surfaces of your
body and organs, inside and
out. They primarily serve as
protective barriers. Skin is
one example.
Nerve tissue carries
messages back and forth
between the brain and
every other part of the
body. The brain, spinal
cord, and nerves are
made up of nerve tissue.
Muscle tissue can
contract, or shorten.
Because of this, muscle
tissue makes parts of your
body move.
LEVEL THREE: ORGANS
WHEN A BUNCH OF DIFFERENT TYPES OF TISSUES WORK
TOGETHER, THEY FORM AN ORGAN. THERE ARE MANY
ORGANS IN THE BODY. HOW MANY CAN YOU NAME??
GET IT????
LEVEL FOUR: ORGAN SYSTEMS
Each organ in your body
is part of an organ
system, a group of organs
that work together to
perform a major function.
For example, your heart
is part of your
circulatory system, which
carries oxygen and other
materials throughout your
body. Besides the heart,
blood vessels are organs
that work in your
circulatory system.
The nervous system detects
and interprets information from
the environment outside the
body and from within the
body; controls most body
functions.
The immune system fights
disease.
The excretory system
removes wastes.
The endocrine system
controls many body
processes by means of
chemicals, like hormones.
The muscular system
enables the body to move;
moves food through the
digestive system, and keeps
the heart beating.
The skeletal system supports
and protects the body, and
works with the muscular
system to allow movement;
makes and stores blood cells
and stores some other
materials.
The digestive system takes
food into the body, breaks the
food down into smaller
particles, and absorbs the
digested materials.
The respiratory system takes
oxygen into the body and
eliminates carbon dioxide.
The reproductive system
produces sex cells that can
unite with other sex cells to
create offspring; controls
male and female
characteristics.
LEVEL 5 – ORGANISMS
ENTIRE LIVING THINGS THAT CAN CARRY
OUT ALL BASIC LIFE PROCESSES.
ALL OTHER LEVELS FORM TOGETHER TO
MAKE ORGANISMS
• PROTISTS
• PLANTS
• ANIMALS
• HUMANS
LET’S REVIEW….
• 1ST LEVEL: CELLS
WORKING TOGETHER
FORM
• 2nd Level: Tissues,
which can form
• 3rd Level: Organs,
which work
together to form
• 4th Level: Organ
Systems, which work
together to form
• 5th Level: Organisms!
