Describe process of thermoregulation Complete the sentences describing the role of skin in regulation of body temperature. eccrine sweat sebaceous shivering sweating cerebral cortex merocrine sweat homeostasis vasoconstriction vasodilation hypothalamus As a part of maintaining ______, body temperature is closely regulated. A change in body temperature is detected by receptors in the ______ of the brain, which then sends signals to effectors in the skin. An increase in body temperature results in _____ of blood vessels in the dermis of the skin, allowing heat carried by the blood to dissipate. An increase in body temperature also causes the nervous system to stimulate ______ glands to increase their activity. A drop in body temperature triggers _______, reducing blood flow and, therefore, heat loss from the skin. If a drop in body temperature is great enough, skeletal muscles are stimulated to begin _______, a mechanism that generates body heat.Explanation / Answer
As a part of maintaining homeostasis, body temperature is closely regulated. A change in body temperature is detected by receptors in the hypothalamus of the brain which then sends signals to effectors in the skin.
An increase in body temperature results in vasodilation of blood vessels in the dermis of the skin, allowing the heat carried by blood to dissipate.
An increase in temperature also causes nervous system to stimulate eccrine sweat glands to increase their activity.
A drop in body temperature triggers vasoconstriction reducing blood flow and therefore heat loss from the skin
If a drop in body temperature is great enough, skeletal muscles are stimulated to begin shivering, a mechanism that generates body heat.
