Why is the circulatory system
important to the respiratory
system?


The circulatory system transports the blood to
all parts of the body picking up waste from the
cells and delivering oxygen to the cells.
The respiratory system filters the waste out of
the blood and refills it with oxygen as it flows
through the lungs.
Why is the circulatory system
important to the excretory
system?


The circulatory system transports waste from
the cells through out the body in blood to the
excretory system.
The excretory system gets rid of the waste
depending on what type it is.
What is the function of the
circulatory system?


To pump blood through out the body
To pick up waste and deliver oxygen to the cells
through out the body
What is the function of the
respiratory system?

To help an organism breath by taking in oxygen
and getting rid of carbon dioxide
What is the function of the
heart?

To pump blood through out the body
What is the function of the
blood vessels?

To transport blood through out the body
What is the function of the
blood?


To supply oxygen and nutrients to all the cells in
the body.
To transports waste from the cells to the
excretory system
What is the function of the
lungs?


To exchange carbon dioxide and oxygen in the
blood
To supply air for the individual to breath
What is the function of the
alveoli?


Small air sacs that hold oxygen for the arteries to
pick up
Small air sacs that hold carbon dioxide until
body exhales it
Muscle Control




Voluntary musclesmuscles that you are
able to control
Examples are leg and
arm muscles
Involuntary Musclesyou can not move them
consciously. They just
keep working
Examples- heart
What system is this? What is it’s
function?
Skeletal System
Gives the body shape,
support and protects
vital organs
This is an internal
skeleton (found inside
the body)
What system is this? What is it’s
function?
 Muscular
 Allows
movement in
the body
 Muscles that move
bones are voluntary
because you can
control the movement.
What system is this? What is it’s
function?


Nervous
Sends / receives messages
through out the body to
control body functions.
If you get hurt in the lab what is the first
thing you should do?

Tell the Teacher
Explain how the skeletal, muscular, and
nervous systems work together when a
person is exercising.
 Skeletal
system supports the body
 Muscular system helps the body to
move
 Nervous send the messages for
movement to occur
When cutting the chicken wing you
always move the scalpel, scissors _____
from your body.


Label each type of joint below..
 Pivot
 Gliding
 Ball
and socket
 Hinge
Blood cells are formed in the bone
_______________________________
____.

Marrow
The name of the structure that connects
the bones to joints is called the
_______________________________.

ligaments
Identify the type of joint which enables us to
make the motions listed:






Turning your head ______________________
Swinging your legs in any direction
_______________________
Finger movement _________________
Movement of your wrist and ankles
____________________
A living bone is covered by a membrane called the
_____________________.
The same tough, flexible material that makes up a sharks
skeleton and a humans ears, and tip of your nose is called
___________________
Body System
Function
Transports materials to and from the body cells
Exchanges oxygen and carbon dioxide gases
Enables the body to move: keeps the heart beating
Sends messages through out the body
Supports and protects the body: makes blood cells
Supports and protects the body: makes blood cells
Label the type of joints seen in the
pictures below.
Word Bank: marrow, muscles,
phosphorus, support, calcium, internal
Gives Shape and _________ to your body.
 Protects your ________ organs
 _________ are attached to bones to help them
move.
 Blood cells are formed in the bone
__________.
 ___________ and _________ are stored in the
bones.

Use the formula to calculate the work
performed in the pictures below. Be sure
to show your work.
Use the formula to calculate the work
performed in the pictures below. Be sure
to show your work.
Use a flow chart to show the
transformation of energy from
the sun to your meal.
How has plant life been affected
during our summer drought?
 It

will wilt from lack of water, then
it will die
Relate a wilted plant to
turgor pressure.
As the cell fills with water, it pushes out onto
the plant’s cell wall (turgid- high turgor
pressure).
 As cell loses water, it does not push out on cell
wall and this causes the plant to wilt.(flaccid- low
turgor pressure)

How does gravity affect directional
growth on roots and stems in a seedling?

Positive Geotropism: roots
always grow
down due to gravity
pulling, but stems always
grow up as Negative
Geotropism
Describe the plant response
to a light during phototropism
 Phototropism:
plants grow
toward the light.
How would birds be different if their
bones make-up were similar to
humans?

Bones would be solid, dense

Unable to get off of ground due to weight
So, What is a force?
A force is a push or pull
Force gives an object the energy
to move, stop moving,
or change direction.

Two forces that are very common are:

Gravity- a force that pulls all objects towards
the center of the Earth.

Friction – a force that resists motion between
two surfaces that are in contact.
What would happen during a game of
tug of war, if two teams exerted the
same amount of force on the rope?
The two forces would cancel each other
out and the result would be no motion
Unbalanced forces are not equal and this causes motion
When two unbalanced forces are
in opposite direction, the net force
is exerted in the direction of the
larger force (subtract)
15 Newtons (N)
40 Newtons (N)
Net Force
25 Newtons (N)




Mechanical

Energy that causes a new substance to be
form, chemical reaction
Food
Fire Cracker
Stomach
Battery
Electrical Energy

Moving electrical charges that produce
electricity and energy.
Static Shock
Lightening
Computers/TVs/
Radios
Lights
Mechanical Energy

Physical Energy associated with the motion of
an object.
Chewing
Sound
Frog Dancing
When is Work Really Work?


In science you do work on an object
when you exert a force on the
object that causes the object to
move some distance.
If the object does not move, no
work is done no matter how much
force is exerted.
