To develop goosebumps the thermoreceptors, (a) will get respond to stimuli like cold temperature. The stimuli signal is sent to the hypothalamus, (b) , which responds by sending a signal to the arrector pili, (c) , to pull on the hair follicle of each hair to reduce airflow to the skin preventing loss of heat.
According to the feedback loop, what does high blood sugar promote?
Insulin Release
Glucagon Release
Insulin Uptake
Glycogen Uptake
Identify each of the types of heat loss by matching the word to the definition
convection
radiation
evaporation
conduction
Put the following fever scenario steps in order
Endogenous pyrogen is released from lymphocytes raising the thermoregulatory set point in the hypothalamus to maintain a higher body temperature!
Higher body temperature causes the spleen and liver to hang onto their supplies of iron; Reducing the levels of iron in the blood.
Bacteria and viruses need iron in the blood to thrive as temperatures rise
Lack of iron and higher body temperatures will cause the bacteria/viruses growth/proliferation to slow to a stop!

swelling
