Homeostasis Disease Feedback Mechanisms Pathogen

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 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? _______________________________________________________
