|
feedback loop
|
|
|
What kind of alert does a receptor send out?

|
|
What form does an effector can be in?
|
muscle or gland
|
|
|
What is the sequence of whole process?
|
1. receptor send out alert.
2. Control center takes it and sends out an order. 3. Effectors take the order and correct the problem. |
|
|
Two types of feedback loops:
|
1) Negative feedback loop
2) |
|
|
Negative Feedback loop
|
a response that is opposite of the problem ( lowers the temperature)
|
|
|
TSH, a chemical, dwindles in blood levels. The body starts to make more TSH chemicals. This is of which example?
|
Negative Feedback control mechanism
|
|
|
Positive feedback loop
|
a response that encourages more of the problem
|
|
|
During peeing, uterine contracts from the chemical oxytocin. The body produces more oxytocin causing you to pee more. This is of which example?
|
Positive feedback control
|
|
|

feedback and loop? |
Feedback happens once and
loop is whole process continuing. |

Seek shade, fan air, and change clothes
|
|
|
What is the purpose of getting all sweaty?
|
Sweat evaporates on the skin, cooling the body down.
|
|
|

|
blood moves from the surface to save heat

|
|
Why do we shiver?
|
Muscles contract to make heat
|
|
|
What is difference between peripheral vasoconstriction and Peripheral vasodilation?
|
A) Blood move from surface
B) Blood move towards surface |
