Homeostasis Flashcards
1
Q
What is a negative feedback loop?
A
A reaction which leads to a decrease or change in the effect.
2
Q
What is an open circulatory system?
A
The lack of blood vessels limited the control of temperatures
3
Q
What is a closed circulatory system?
A
The vasomotor controls the dilation and constriction of blood vessels, giving more control over temperature.
4
Q
What are the physiological strategies for thermoregulation?
A
Shivering, vasoconstriction and vasodilation, BAT (brown adipose tissue breaks down to create heat).
5
Q
What are the behavioural strategies for thermoregulation?
A
Posture change to increase and decrease surface exposure, temperature choice, altering the microenvironment such as by huddling
