Homeostasis
The ability of an organism to maintain a stable internal environment.
What is homeostasis!
temperature stress
heat and cold stress
Often serves as the coordinating center:
Receives messages from monitors
Initiates a hormonal/nervous response
hypothalamus
Disrupts homeostasis
What is disease, illness, enviroment
Lack of insulin function which causes elevated glucose levels in the bloodstream
What is diabetes
Little to no insulin is released
What is type 1 diabetes
Response triggered by changed conditions serves to reverse the change
Negative feednback
These are some aspects of the body that must be maintained in order to achieve homeostasis.
What is pH, Body Temperature, and Blood Sugar!
The two of diabetes
Type 1 and Type 2
Components of a homeostatic control system
Monitor
Coordinating centre
Regulator
Body tempture
Negative feedback
This is an example of homeostats
blood sugar, thermoregulation, contractions
This is a negative loop
What is glucose regulation in the blood
Homeostasis is also called this
dynamic equilibrium
Child birth
Positive feedback
If homeostasis is not achieved this can occur...
What is death!
The feedback loop that regulates temperature
What is negative feedback
The control of body temperature, contractions and the concentration of sugar are
Feedback mechanisms
—How is dynamic equilibrium maintained?
Feedback systems
This is the maintenance of body temperatures within a range that enables cells to function effectively
thermoregulation
