Temp Range/neg Feedback Flashcards
1
Q
How is it controlled ?
A
Feedback loops
Allow organisms to maintain homeostasis
2
Q
Negative feedback loops
A
Detect change and responds and corrects them
species use them to stay the correct temp
3
Q
Endotherms
A
Species that regulate their own body temp.
Bad- need more food more often
4
Q
Heat gain/heat loss centre
A
When’s animal is too hot- heat loss centre activated
When animal too cold- heat gain centre
5
Q
When too cold?
A
1.thermoreceptor detect body temp is too cold by hypothalmus
2. Heat gain centre activated
3.effectors from feedback loops make u shiver
6
Q
Too hot?
A
Thermorecptor detects body temp is too hot in hypothalamus
Heat loss centre activated
Effectors from feed back loop make you sweat
7
Q
Ectotherm
A
Can’t regulate own body temp
Less food
Certain Climates
