CONCEPT MAP

 

            Key Concepts:                                                                                   Key Vocabulary:

 

Homeostasis

Disease

Feedback Mechanisms

Pathogen

Guard Cells

Insulin/pancreas

Antibody/Antigen

Dynamic Equilibrium

White blood cells

 

 

 

 

 

 

 

 

 

 
                                                                                                                       

Pathogens infect plants/animals and interfere with life functions

 

 

Immune system is designed to protect against antigens (white blood cells)

 

                                                           

Topic: Disease as a Failure of Homeostasis

 

 
AIDS, allergy, transplant

Immune responses and homeostasis

 

 

Feedback mechanisms maintain homeostasis

 

 

 

 

Examples:

Pathogens = viruses, bacteria, protests, fungi

WBC: some engulf pathogen, others make antibodies

Overactive or underactive immune system

Feedback ex – guard cells, glucose and insulin, heart rate, and muscle act.

 

 

 

 

 

 

 

 

 

 

 

 

 

Enduring Understanding (s): Disease is a disruption of Homeostasis.  Feedback mechanisms maintain internal environment within narrow limits. _________________________________________________

 

 

Essential Question (s): Why do we get sick?  Why do we get a fever when sick?  How can non-living things cause illness in people?  How is cruise control like Homeostasis?  _______________________________________________________
