thermoregulation

Examples of thermoregulation in the following topics:

• Thermoregulation

  • The integumentary system keeps body temperature within limits even when environmental temperature varies; this is called thermoregulation.
  • The process of skin-based thermoregulation occurs through several means.
  • The body also thermoregulates via the process of sweating (perspiration).
  • In addition, our body thermoregulates using our hair. 
  • While this hair-based method of thermoregulation is effective in many mammals and birds owing to their large and thick amounts of fur and feathers (respectively), the relative effectiveness of this method of thermoregulation in humans is in question since we have little to no body hair in comparison.

• Blood Flow in the Skin

  • These muscles are under the control of the sympathetic nervous system and provide an efficient means of thermoregulation through vasoconstriction and vasodilation.

• Excretion and Absorption

  • Eccrine glands are active in thermoregulation and are stimulated by the sympathetic nervous system.

• Local Regulation of Blood Flow

  • For example, more blood is directed to the skeletal muscles, brain, or digestive system when they are active, and blood flow to the skin can be reduced or increased to aid with thermoregulation.

• Functions of Blood

  • Other functions include pH regulation and thermoregulation.

• Blood Vessel Function

  • Mechanically the blood vessels, especially those near the skin, play a key role in thermoregulation.

• Waste Management in Other Body Systems

  • The sweat glands remove a bit of excess water and salts, and also serve the function of cooling the body during thermoregulation.
