Learning objective: Students will be able to Explain what happens in one body system can
have an effect on other body systems. Generate new and productive questions to evaluate
and refine core explanations.
• Build a model that represents the interdependence of the human body’s major systems in
regulating its internal environment.
• Compare and contrast the human body systems.
• Determine how the interdependence of the body systems achieve homeostasis.
Enduring understandings: Various systems are interdependent of each other. All body
systems are interrelated in order for a body to function. Healthy Systems have limits. How
does interdependency influence and apply to various systems? Why is no one body system
independent of the others?
