What organs are involved in
the Nervous System?
Brain, spinal cord and
nerves.
What are the three jobs of
the Nervous System?
1. Receive information from
the external environment
2. Respond to information
3. Maintain homeostasis
If you are reading a book,
what part of your brain is
helping you?
Your Cerebrum
A nerve impulse enters
through the ___________
of the neuron.
Dendrite
What organs make up
your central nervous
system?
Brain and Spinal Cord
What organs are involved
in the Circulatory System?
Heart, blood and blood
vessels
What are the two jobs of
the circulatory system?
Bring needed substances
to cells, and to carry waste
away from cells.
Your heart is a hollow
___________ that pumps
blood your whole life.
Muscle
What are the four things that

Red Blood Cells
White Blood Cells
Platelets
Plasma
List how blood flows through
the body starting with the Right
Atrium
Right atrium Right Ventricle
Pulmonary Artery  Lungs
Pulmonary Vein  Left Atrium
 Left Ventricle  Aorta  Body
 Vena Cavas
What are the two jobs of the
respiratory system?
Moves oxygen into the body
and removes carbon dioxide
and water.
How are your lungs able to
take in so much oxygen?
Due to the large surface area
of the alveoli.
What is the large muscle that
controls your breathing?
Diaphragm
This is the part of the
respiratory system that is
shared with the digestive
system, also known as your
throat.
Pharynx
What is the process that
allows the carbon dioxide in
the blood to move into the
alveoli and the oxygen to
move into the blood?
Diffusion

The septum
Describe how the circulatory
system and respiratory
system are related using the
following words:
alveoli, lungs, oxygen,
carbon dioxide, capillary,
heart, and body.
Example:
When you inhale, you bring oxygen into your lungs.
Inside the lungs, the alveoli fill with the oxygen. The
capillaries that cover the alveoli contain blood high in
carbon dioxide. The oxygen leaves the alveoli and
enters the blood. The carbon dioxide leaves the blood
and goes into the alveoli. The capillaries then carry the
oxygen rich blood back to the heart to be pumped to the
body. The carbon dioxide in the alveoli gets exhaled out
of your body.
Describe how a nerve impulse travels
through a neuron using the following
words: dendrite, axon, axon tips, cell
body, nerve impulse, neurotransmitter,
synapse, dendrite of next neuron,
electrical, chemical
A nerve impulse starts out in a dendrite. It then
travels though the cell body and then into the
axon. Then the impulse reaches the axon tips.
In order to cross the synapse, neurotransmitters
are released to change the impulse from
electrical to chemical. The neurotransmitters go
across the synapse and reach the dendrites of
the next neuron. The impulse converts back to
an electrical impulse and the impulse continues
on.
Fill in the blanks.
A ________________ starts in a sensory
neuron. The impulse travels up to the brain
through _______________. Then the nerve
impulse travels to a _______________.
The motor neurons send the impulse to a
_____________ which then contracts.
A nerve impulse starts in a sensory
neuron. The impulse travels up to the
brain through interneurons. Then the
nerve impulse travels to a motor
neuron. The motor neurons send the
impulse to a muscle which then
contracts.
