System Function (what it does)
Organs (tissues together that perform a specific function)
Picture Homeostasis(The body’s way of regulating equilibrium – staying balanced)
Controls thinking, senses, & regulates homeosta
sis
Brain and spinal cord,
sensory organs
and nerves
Nervous SystemFunctions Organs Picture Homeostasis
S: A person touches a hot stove.
R: A person’s body sends a message to move their hand.
Slap JackPlay slap jack 3 times with your partner. Break the stack of
cards in half each person turns over a card and puts it in a pile between the two players, when a jack card turns up be
the fastest player to slap the jack. Then take the cards under the jack, the player with the most cards at the end
wins.
1.What major organs of the nervous system did you use to play?
2.What function(s) of the nervous system did you use?3.How are your reflexes and the nervous system
connected?4.What are the levels of organization specific to the
nervous system?5.What is the stimulus and response to playing Slap Jack?
Regulates body
temperature, sensory response,
rids body of waste and protection
Skin, sweat
glands, & hair
Integumentary (Skin) System
S: A person walks outside while it is snowing wearing shorts.
R: A person get chill bumps and begins to shiver.
Helps body stay
healthy by fighting of
germs, diseases,
and micro-organisms
Lymph glands, vessels, and fluid
Lymphatic (Immune) System
S: A germ is swallowed when a person eats with dirty hands.R: A person’s temperature increases and then vomits.
Breaks down food
and absorbs
nutrients the body
needs
Mouth, esophagus, stomach,
small intestine,
large intestine, and anus

Move (transport
s) materials
(O2, nutrients,

Circulatory System
Blood pressure – force blood exerts on walls of veins
S:Plaque begins to stick to artery walls, narrowing the vessel.
R:Blood pressure increases.
1.What does the pipette, the water, and balloon represent in this model of the circulatory system?
2.The action of applying pressure to and releasing pressure from the pipette demonstrates what function of the circulatory system?
3.What is a limitation of using this model as opposed to the human body?
4.Place a bean in the balloon, what does the bean represent?
5.What would happen if you squeezed water through the pipette leaving the bean in the balloon, how would the experiment be different?
Reinforcement:1.In your own words write the function for the
circulatory system.2.Rank the three main structures of the
circulatory system and give the reason for your rankings.
3.While running outside you stop to rest at a park bench, what happens to your heart rate while you are resting on the bench?
4.Using the scenario above how would the heart rates be different if we compared the rates of a 300 lb. woman to a 140 lb. woman? Explain your answer.
Breathing (Inhale – oxygen,
O2; exhale – carbon dioxide,
CO2)
Nasal cavity,
trachea, bronchi, lungs, alveoli,
diaphragm
Respiratory System
S: A person visits a mountain so high that the air is very thin.
R:A person must increase the breathing rate to sustain normal oxygen levels.
Lung Capacity1. What are the independent and
dependent variables used when finding lung capacity?
2. What type of graph would you create to show the collected data?
3. Put in your own words the meaning of lung capacity.
4. Why would it be important for someone to know there lung capacity?
Structure, support,
protection, stores
