system interactions brought
about this response?

challenge of climbing higher. What
happens in your body to maintain
stability under extreme physical
exertion at high altitudes?
Upon returning to school after the
summer break, you notice that the
student whose locker is next to

though he could be in a body building
competition. What happened in his
body to create these physical
changes?
You eat a chicken nugget meal
from Chick-Fil-A. What processes
must occur to enable biomolecules
from the food to be transported

You are walking in the woods and
stumble across a bloody,
disfigured human body (not
really…you saw this on C.S.I.). You
turn away to run, but instead you

threatening urgency of the
bowels. You slump in a faint. What
happened in your body to cause
these extraordinary reactions?
Body System Interaction Scenario Cards - Partner Activity
You and your partner will work together to do the following:
You must choose 4 out of the 12 given scenarios. For each scenario:
1. List each body system that is at work. You must explain how the body system is functioning and
the main organs that the body system is using. In your explanation, explain how various body
systems and organs are working together.
2. List any body system that might be suppressed. Explain why.
3. Is this an example of positive feedback or negative feedback? Explain why.
Example
Scenario: You are a deep sea diver who loves the thrill of diving in deep waters to explore sunken
treasures. You are careful to follow all the rules of diving including monitoring how much air you have
in your tank and how long you can stay deep down. Without warning, your gauges fail, leaving you
without information about the air in your tank. What is happening in your body to help you survive?
1.
Nervous-Various parts of the brain are controlling the rate of respiration, movement of muscles and bone,
and decision making about what the body should do. The brain stem is regulating respiration (respiratory
system) so that they body can maintain proper oxygen levels in the body. The cerebrum is moving the
muscles of the muscular system and bones of the skeletal system so that the body can swim to the surface
of the water. The cerebellum is working to control your decision making process.
Respiratory-The lungs are ridding the body of carbon dioxide and bringing in oxygen. The brain stem of
the nervous system senses an increase in carbon dioxide, sends a signal to the diaphragm to contract, which
forces the lungs to expand and oxygen to enter the alveoli of the lungs.
Circulatory-The capillaries, surrounding the alveoli in the lungs (respiratory system), are absorbing oxygen
and sending oxygenated blood through the pulmonary vein back to the heart. Then the heart pumps
oxygenated blood to the body so that they body has the ability to swim to the surface.
Muscular-The muscles are moving the bones of the skeletal system so you can swim to reach the surface.
Skeletal-The bones are being moved by the muscles of the muscular system so that you can swim to reach
the surface.
Endocrine-The adrenal gland is producing the hormone adrenaline which triggers the body’s response to this
sudden stress. The brain of the nervous system is controlling the release of this hormone.
2. Digestive system. Adrenaline production decreases the activity of the digestive system.
3. Negative feedback. Your respiratory and circulatory systems are working together to exchange carbon
dioxide and oxygen to maintain an equal balance of both in the in the body.
