Thermoregulation

What is homeostasis in the context of body temperature?

Homeostasis refers to keeping the body in a steady state or equilibrium, with the optimum operating temperature being 36-37.5 degrees.

What is thermoregulation?

Thermoregulation is the process by which the body maintains its optimal temperature of around 37 degrees.

Where is the thermoregulatory center located?

The thermoregulatory center is located in the hypothalamus.

What are the two sets of thermoreceptors used in thermoregulation?

Receptors in the hypothalamus and thermoreceptors in the skin.

What is hyperthermia?

Hyperthermia occurs when the body gains more heat than it can lose.

What is hypothermia?

Hypothermia occurs when the core temperature falls below the level required to maintain minimum metabolic functions.

What are the four methods of thermoregulation?

The four methods are radiation, evaporation, conduction, and convection.

How does the body cool itself through sweating?

Warm blood is directed to the skin via vasodilation, where sweat evaporates, absorbing energy and cooling the blood.

What happens to blood vessels during dehydration?

Surface blood vessels constrict, stopping sweat production to preserve blood volume.

What is the role of shivering in thermoregulation?

Shivering generates heat from muscle activity as a protective mechanism.
