Homeostasis
The ability of an organism to maintain a stable internal environment.
What is homeostasis!
If your body temperature gets too hot, what does your body do to bring the temperature down?
Give two answers. *200 points each*
2) blood vessels dilate and allow heat to leave skin easier (skin flushes)
A part of the "lizard" brain that often serves as the coordinating center for the body. Specifically it is in control of regulating body temperature among others.
the hypothalamus
What do you call something that disrupts homeostasis?
What is disease, illness, or an environmental change.
Lack of insulin function which causes elevated glucose levels in the bloodstream
What is diabetes
What occurs if someone is born with Little to no insulin is released by their pancreas?
What is type 1 diabetes
Response triggered by changed conditions serves to reverse the change... brings back to a Neutral point.
Negative feedback
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 types of diabetes
Type 1 and Type 2
Components of a homeostatic control system
Stimulus (environmental change)
effector (organ that recieves message and causes a change)
response
Body temperature
Negative feedback
This is an example of homeostats
blood sugar, thermoregulation, contractions
Give an example of negative feedback.
What is glucose regulation in the blood
Homeostasis is also called this
d___________ e____________
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
What is a feedback Mechanism?
a regulatory function of the body.
How is dynamic equilibrium maintained (homeostasis)?
Feedback systems
This is the maintenance of body temperatures within a range that enables cells to function effectively
thermoregulation
