The Integumentary System: Thermoregulation In The Human Body

The Integumentary system maintains the body’s temperature, homeostasis, and delivers sensory information. Hair, nails, skin, glands and nerves are all part of the integumentary system. The integumentary systems main functions are to protect and keep the body safe from all external environments. Furthermore the roles of the integumentary system are to help control the body temperature, remove any unwanted toxins in the body and fight against any illness or disease. Thermoregulation is a function in the integumentary system as it is a procedure that enables your body to maintain its temperature. It is the power of an organism “to keep its body temperature within certain boundaries, even when the surrounding temperature is very different.” (CITE
It does this by responding distinctively to hot and cold environments so the core body temperature stays pretty much stable. Keeping up the internal body temperature of the human body is essential for “basic survival, regulation of enzymes involved in reactions within our body and as a hostile environment used as a defensive mechanism against invading pathogens.” (CITE) Internal body temperature is a negative feedback mechanism, implying that the body responding will represent any adjustment in the internal body temperature outside the ordinary homeostatic range, whether the temperature will increase or decrease. In spite of the fact that there is a set homeostatic range for temperature, under ordinary conditions the human body is continually fluctuating inside the set range. This implies it is never at a steady perpetual body temperature. Many components can influence your body's temperature, such as being in cold or hot environments. Influences that can increase your internal temperature are “fever, exercise and digestion.” (CITE) Influences that can decrease your internal temperature are “drug use, alcohol use, metabolic conditions; such as an under-functioning thyroid gland” (CITE) Your hypothalamus is an area of your mind that controls thermoregulation. When it detects your core temperature increasing or decreasing, it sends signs to your muscles, organs,
The sympathetic nervous system is constantly observing body temperature. Sweat glands, secrete water, salt and different substances to decrease and cool the body when it turns out to be warm. Even though the body does not physically look to be sweating, it is still secreted. In the result that the body turns out to be too much warm because of high temperatures, highly intense physical activities will result in sweat organs that are triggered by the sympathetic nervous system to create a lot of sweat. At the point when the sweat vanishes from the skin surface, the body is cooled as body warm is dispersed.
Furthermore in regards to sweating, arterioles in the dermis enlarge with the goal that an overload of heat transmitted by the blood can spread through the skin and into the environment. This explains when individuals work out and redness appears on the
