Question

impotance of thermoragulation

Answer 1

in humans. ... As in other mammals, thermoregulation in humans is an important aspect of homeostasis. In thermoregulation,body heat is generated mostly in the deep organs, especially the liver, brain, and heart, and in contraction of skeletal muscles.

Thermoregulation is a process that allows your body to maintain its core internal temperature. All thermoregulation mechanisms are designed to return your body to homeostasis.

Importance of thermoregulations;

* Regulate internal body temperature.

If thermoregulation does not operate properly it may result in fever. This can be caused by the presence of endogenous substances like pyrogen. Pyrogen affects the activity of the pre-optic thermosensitive neurons.

* Maintain skin blood flows

preoptic area is able to coordinate correct efferent response in response to various internal and external thermal stimuli. One of these responses is the control of skin blood flow in humans. The vasodilation of blood vessels and the resultant increased blood flow to the skin is vital to heat dissipation during heat exposure. The increased skin blood flow significantly increases convective heat transfer from the body to the periphery.

* Behavioural thermoregulations

Behavioural responses to changes in environmental temperature occur before the internal body temperature elevates. It is from this that the assumption has been made that receptors in the skin play a key role in behavioural thermoregulation. Research has shown that the neurons responding to thermal stimulation of the skin are located in the spinal cord, with the signals from these reach areas in the cerebral cortex.

* Adapting to the environment
