Body Systems Study Sheet
Be able to distinguish between learned behaviors and instincts. Below are some examples:
Learned Behaviors
A cat using a litter box
A dog fetching a stick
Tiger sneaking up on prey
Playing the piano
Speaking Italian
Instincts
A baby crying for milk
A fish swimming in water
A spider making a web
A bird building a nest
Caterpillar making a cocoon
Be able to distinguish between unicellular and multi cellular organism
Unicellular Organisms





(also known as single – cellular)
Unicellular organisms consist of a single cell that
performs all life processes.
If a unicellular organism has a single cell damaged it
will die.
The organism has the ability to produce offspring
It is made up of a cell that links with other similar
cells to form a colony
Bacteria is a unicellular organism
Multicellular Organisms

Multi cellular organisms have well developed
transport systems because all cells of a multicellular
organism are not in direct contact with the outside
environment for the exchange of substances.
The surface cells are in contact with the external
environment
Energy produced in one cell is transported to
another cell
If a multi-cellular organism has a single cell
damaged it can survive and make new cells.
Different cell types of the organism perform different
functions in a multicellular organism
The organism has the ability to produce offspring
. Simplest multicellular organisms are made of cells
that dependent on each other for their survival. Most
of the multicellular organism are microscopic and
are known as microscopic organisms.
Multicellular organisms need transport systems because cells inside the organisms need to exchange substances with the
outside environment.
Cells are the basic unit of life. Many cells make up tissues, tissues make organs and organs make up systems.
Be able to recognize an inheritable trait
Inheritable Traits
Non- Inheritable Traits
Height
There are scars on one hand
Hair color
Ability to play the piano
Ear lobes
There is jewelry on one hand
Dimples
Blue hair in humans
Eye color
Talkative
Finger types
Ability to ride a bike
Toe types
Like Mexican food
Gender
Length of hair
Long whiskers
In offspring the mixing of parental characteristics is caused by the fact that each offspring receives a
different combination of genes from their parents (remember the gingerbread family)
Parents and offspring are similar by both inherited traits and learned traits.
Be able to identify the order in which food is digested in the digestive system.
Which body systems work together?





Skeletal & Muscular System work together to help you move.
Respiratory & circulatory System work together to help you transport gases.
Digestive and excretory system work together to remove waste.
Nervous system works with all systems because it is the control center or brain of the entire body.
Digestive system and muscular system work together to move food through the body.

Digestive System
The digestive system processes food
into a useable source of energy
Digestion begins in the mouth with
Chewing (mechanical) and
saliva(Chemical) break down of food.
Nutrients released from food in the
small intestine are transported by the
circulatory system to other parts of the
body.
The digestive system and the
muscular system work together to help
move food through the digestive track.

Skeletal System
Supports and Protects the body
Gives Shape to the body
The skeletal system protects most
of the delicate organs of the body.
The skeletal system, muscular
system and nervous system work
together to help a person move.
Produce blood cells in bone
marrow.



Circulatory System
The function of the cardiovascular
system is to transport gases
throughout the body
The cardiovascular system works with
the respiratory system to transport
fresh oxygenated blood to the cells
and remove harmful waster (Carbon
dioxide) from the body.
The heart pumps blood throughout the
body
White blood cells are like your
personal army. They fight infections
and diseases.
The circulatory system supports the
digestive system by transporting
nutrients to all cells in the body.
Muscular System
The muscular system, skeletal
system, and nervous system work
together to help a person move.
Cardiac Muscles pump and circulate
blood throughout the body
Together, the skeletal muscles work
with your bones to give your body
power and strength.
DNA is found in the nucleus of both plant and animal cells.

Nervous System
The nervous system allows your body
to feel pain so you can respond to
stimuli correctly.
The primary function of the nervous
system is to control the different
systems of our body
The human brain is formed of the
cerebrum, cerebellum, limbic system
and brain stem.
The Nervous system is also known as
the message transport system of the
human body.
The nervous system sends electrical
signals to all other body systems.
Excretory System
The excretory system is a collection of
organs that work in unison to remove
waste and other harmful products from
the body.
The excretory system helps keep the
internal environment of the body
clean. It helps remove water along
with excess salts and water.
The excretory system is aided by the
circulatory system in its proper
function.
