Too hot or too cold …
What responses does the body have to temperature?
How does it respond when it is too hot?
How does it respond when it is too cold?
Slide3
How temperature is controlled in the long term…
The hormone
thyroxine
increases the metabolic rate and increases heat production.
Thyroxine
secreted by the thyroid gland.
When the hypothalamus detects a drop in temperature it secretes
thyrotrophin
releasing hormone (TRH)
TRH stimulates the production of thyroid stimulating hormone (TSH) which stimulates the production of
thyroxine
.
Thyroxine
results in the production of more mitochondria. This leads to a greater rate of respiration and more heat being released.
This method takes a lot of time and tends to take place over a couple of days.
