Bob is running a marathon which expends a great deal of energy. Much of this energy generates heat, which then increases his core body temperature. He is in your clinic for treatment of dehydration. Bobbie is sitting at a football game in late November when it is very cold. Her skin is very cold but her core temperature remains constant. She is being seen today for frostbite.
What are three ways the integumentary system helps regulate body temperature in these examples? Briefly describe the role of the integumentary system in combating each of the diagnosis above.

Answer:

1-by dilating blood vessels to release heat (radiation)

2-by constricting blood vessels to retain heat (radiation)

3- by interchanging heat with the environment (convection)

4-by increasing sweat evaporation (perspiration)

Explanation:

The integumentary system helps to maintain body temperature within certain boundaries, thereby maintaining a relatively constant-homeostatic state. The integumentary system contains an important amount of blood vessels in the dermis, i.e., the middle layer of the skin, that act to decrease body temperature via vasodilation (i.e., by expanding the size of these vessels), thereby releasing heat through a process known as radiation. Convection is another process that helps heat loss by the circulation of air in contact with the skin. Finally, by the process of perspiration (sweating), the integumentary system can also release heat when the body's temperature up above its normal level (36.5°C). This sweat production can be increased or lowered depending on the environmental conditions (i.e., excessive heat and cold, respectively).
