When a bacterium is destroyed by phagocytic white blood cells, it is called Endogenous pyrogens are released into the blood. These pyrogens circulate to the hypothalamus and reset the thermostat. This allows the body’s temperature to rise in a condition commonly known as a fever.
What resets the hypothalamic thermostat?
Treatment of fever depends on use Antipyretics (Tylenol, Aspirin, etc.) All of these reset the hypothalamic thermostat. Conversely, drugs that suppress sweating (anticholinergics) or flushing (vasoconstrictors) may interfere with the body’s cooling mechanisms and increase fever.
What causes fever by resetting the hypothalamic set point?
Effervescent period: release endogenous pyrogens Raising the hypothalamic thermostatic set point results in an increase in body temperature. When the body begins to produce more heat and lose less heat, the onset of a fever may manifest as chills, shaking, and constriction of the skin’s blood vessels.
How does the hypothalamus respond to fever?
« The hypothalamus responds to different factors, such as infectious organisms and injury, Alters body temperature by releasing fever-producing chemicalsSpecifically, these chemicals cause blood vessels to narrow and carry heat to the innermost parts of the body. The result is a fever.
If the patient has a fever, what will reset the patient’s temperature to the set point?
Increased pyrogenic chemicals in the blood Receptors that are stimulating the upper limit of the temperature of the exothermic response are being stimulated.

How do sweat glands help regulate body temperature?
Sweating plays an important role in the regulation of body temperature When the water in sweat evaporates, by dissipating heat energy from the surface of the skin. Sweat after exercise can counteract heat stress, allowing us to survive extreme climates.
How does the skin regulate body temperature?
blood vessels of the dermis Provides nutrients to the skin and helps regulate body temperature.
