The eccrine sweat gland, which is controlled by the sympathetic nervous system, regulates body temperature. When internal temperature rises, the eccrine glands secrete water to the skin surface, where heat is removed by evaporation.

How does the sweat glands help maintain body temperature?
When heat activates sweat glands, these glands bring that water, along with the body's salt, to the surface of the skin as sweat. Once on the surface, the water evaporates. Water evaporating from the skin cools the body, keeping its temperature in a healthy range.
What are the functions of sweat glands?
Sweat glands occur all over the body, but are most numerous on the forehead, the armpits, the palms and the soles of the feet. Sweat is mainly water, but it also contains some salts. Its main function is to control body temperature. As the water in the sweat evaporates, the surface of the skin cools.
How does sweat glands create or maintain homeostasis?
The eccrine sweat gland, which is controlled by the sympathetic nervous system, regulates body temperature. When internal temperature rises, the eccrine glands secrete water to the skin surface, where heat is removed by evaporation.
What methods are used to maintain body temperature?
When exposed to hot conditions, sweating is one of the primary methods your body uses to control its temperature. Sweat, as it evaporates, helps cool the skin. Blood vessels feeding the skin also dilate, which allows warm blood to flow to the skin surface. This helps remove heat from the body core.
What temperature is sweat?
The sweat helps to cool you off to around 98.6 degrees again.
Which body system is responsible for sweating?
Sweating is controlled by the autonomic nervous system. This is the part of the nervous system that is not under your control. Sweating is the body's natural way of regulating temperature.
What happens to your body when you sweat?
You sweat when you exercise, have a fever, or are anxious. Sweating is how your body cools itself. When your internal temperature rises, your sweat glands release water to the surface of your skin. As the sweat evaporates, it cools your skin and your blood beneath your skin.
How does body maintain homeostasis?
Homeostasis depends on the ability of your body to detect and oppose these changes. Maintenance of homeostasis usually involves negative feedback loops. ... The control center will process the information and activate effectors—such as the sweat glands—whose job is to oppose the stimulus by bringing body temperature down.
How does each body system maintain homeostasis?
the circulatory system helps the body maintain homeostasis by transporting nutrients. The circulatory system works with the respiratory system to exchange carbon dioxide and oxygen. ... the lymphatic system works to help the body maintain homeostasis by regulating fluid buildup in the cells and helps to fight infection.
Which is an example of how the body maintains homeostasis?
Humans' internal body temperature is a great example of homeostasis. When someone is healthy, their body maintains a temperature close to 98.6 degrees Fahrenheit (37 degrees Celsius). ... When you get shivery in the cold, or sweat in the summer, that's your body trying to maintain homeostasis.
What are voluntary and involuntary ways to maintain body temperature?
Voluntary and Involuntary
Some of the responses to temperature are voluntary: We take off our coat when it's too warm. Some are involuntary: We swelter in the heat. Our bodies generate heat in cold weather by muscular contraction -- shivering.
Why do we need to maintain body temperature?
Body temperature must be controlled within a very narrow range so that the body can function properly. In particular, enzymes in a body's cells must have the correct temperature to be able to catalyse chemical reactions. high temperatures can cause dehydration, heat stroke and death if untreated.
How does the body respond to hot and cold temperatures?
When the body is exposed to extreme heat conditions, the body most important mechanism to dissipate heat and prevent an increase in core temperature is sweating but when in cold conditions, in order to prevent hypothermia, the body's main objective is heat conservation predominantly through peripheral vasoconstriction ...
How does the body protect itself from extreme temperatures?
When the body is overheated, the sweat glands are activated to to release heat and cool down the body. When the body senses cold, the blood vessels in the skin constrict and arrector pili muscles are stimulated to form goosebumps, all preventing loss of body heat. ... It's a way to flush out the system and cool the body.
How does sweat evaporation cool the body?
That's because cooling your body via sweating relies on a principle of physics called "heat of vaporization." It takes energy to evaporate sweat off of your skin, and that energy is heat. As your excess body heat is used to convert beads of sweat into vapor, you start to cool down.
What part of the body doesn't sweat?
The human body has approximately 2 - 4 million sweat glands found all over the body, except on the nails, ears and lips. The most concentrated area of sweat glands is on the bottom of our feet while the least concentrated area of sweat glands is on our back.
