what does The thermoregulatory centre have receptors for and what does it do

The thermoregulatory centre which monitors and controls body temperature is found in the brain.

● Has receptors that monitor the temperature of the blood

● Has receptors in the skin that send impulses to the thermoregulatory centre

Human body temperature is 37.5 degrees celsius.

when our body temp becomes high we sweat by increasing what

If it becomes too high: ● Sweat (evaporates from skin surface resulting in increased energy transfer away from body) is produced from sweat glands

2nd thing if high temp in body what is vasodilation

● Vasodilation means more blood flows closer to the surface of the skin, resulting in increased energy transfer from the body

If it decreases too much: what happens

● Sweating stops

● Skeletal muscles contract rapidly (shivering) to generate heat from respiration

● Hairs stand on end to create an insulating layer, trapping warm air

● Vasoconstriction means blood does not flow so close to the surface, resulting in less heat lost
