GENERAL HISTOLOGY

Detailed explanation-1: -Nerves trigger sweat glands to release fluid that evaporates and cools the skin. Conversely, a drop in core temperature makes blood vessels constrict to conserve heat. The nervous system also triggers muscles to shiver to generate heat and warm the body.

Detailed explanation-2: -When the environment is not thermoneutral, the body uses four mechanisms of heat exchange to maintain homeostasis: conduction, convection, radiation, and evaporation.

Detailed explanation-3: -Much like a thermostat regulates the temperature inside your home, the hypothalamus regulates your body temperature, responding to internal and external stimuli and making adjustments to keep the body within one or two degrees of 98.6 degrees.

Detailed explanation-4: -Circulatory mechanisms, such as altering blood flow patterns. Insulation, such as fur, fat, or feathers. Evaporative mechanisms, such as panting and sweating.
