Question

Mr. Shepherd has gone outside to shovel snow on a cold day. How does his body maintain a relatively constant body temperature? What is this process called?

Answer 1

ANSWER.

* Reason for body maintain a relatively constant body temperature in a cold day.

       * When the patient exposed to a cold environment nerve endings sensitive to

        temperature change or thermoreceptors present in the skin send impulses

            to the hypothalamus.

     * Hypothalamus is a area present in the brain helps to maintaining body temperature

      by sending impulses through efferent nerves to the muscles to initiate shivering for

        generating heat.

           * So body start to shiver when exposed to cold temperature which produce enough

          heat to maintain relatively constant body temperature.

* The process by which body maintain relatively constant body temperature is called

Thermoregulation.
