Temperature Control Flashcards
1
Q
How is body temperature controlled and monitored
A
Thermoregulatory centre in brain
2
Q
How does thermoregulatory sensors work
Where do they work
A
It’s centre has receptors sensitive to temperature of blood flowing through brain
Temperature receptors on skin send impulses to the thermoregulatory centre
3
Q
What two things happen if the core body temperature is too high
Explain
A
Blood vessels supplying blood to the skin dilate so that blood flows through the capillaries and more heat is lost
Sweat glands release more sweat which evaporates
4
Q
What two things happen if the core body temperature is too low
Explain
A
Blood vessels supplying blood to the skin (capillaries) contract to reduce blood flow
Muscles contract which needs respiration- releases energy to warm body
