Homeostatic regulation usually involves three key factors to help control homeostasis, what are they?
Definition
(1) a receptor that is sensitive to a particular environmental change or stimulus, (2) a control center, or integration center, which receives and processes information from the receptor: and (3) an effector, which responds to the commands of the control center and whose activity opposes or reinforces the stimulus.

Term
Thermoregulation is what?
Definition
The control of body temperature
Term
What does thermoregulation involve?
Definition
Altering the relationship between heat loss and heat production.
Term
How does your body regulate temperature if it rises?
Definition
The thermoregulatory control center in located in the brain. Temperature receptors are located in the skin and in cells in the control center. Normal temp is 98.6. If it rises, the control center tragets two effectors: (1) smooth muscles in the walls of blood vessels that supply the skin and (2) sweat glands. The muscle tissue relaxes and blood vessels widen that inturn increases blood flow and the sweat glands accelerate their secretion. Skin acts like radiator and loses heat to environment and evaporation of sweat speeds process. Temp returns to normal, thermoregulator center becomes inactive till needed again.
Term
How does the body regulate temp. if it drops?
Definition
The control center targets the same two effectors but this time the blood flow declines and sweat activity decreases. This combo reduces the rate of heat loss to the environment. Due to heat production still continuing in the body the temp. balance with level and everything goes back to normal resting levels.
Term
What is positive feedback?
Definition
It is the initial stimulus produced from a response that reinforces that stimulus.
Term
What is an example of positive feedback?
Definition
Blood clotting. When you get injured and your recieve a cut, the damaged blood vessel wall releases chemicals that begin the multistep process of blood clotting. As clotting gets underway, each step releases chemicals taht accelerate the process. That accelerated process is a positive feedback.
