Sweat, also called perspiration, is a fluid produced by the sweat glands made up of water, minerals, lactate and urea. The minerals that make up sweat can vary from person to person depending on a number of factors. This fluid is used by the body to help cool it when heat builds up inside.Know More
A number of factors influence the types of minerals that are produced in sweat such as a person's acclimation to heat. The more a person is exposed to heat, the more their body adjusts to keep the minerals it needs and remove what it does not. Similarly, the amount of time needed to cool a person's body off can also affect what minerals are released. Minerals found in sweat include sodium, potassium, calcium and magnesium as well as a number of other trace elements such as zinc, copper and chromium.
In addition to humans, all other mammals sweat. However, unlike some species, human sweat is hypoosmatic, meaning it is less salty than plasma. Like horses, humans also produce more sweat than most species of mammals to regulate body temperature. Other species, such as dogs, reduce their body heat by panting and other means.Learn more about Glands & Hormones
According to the Encyclopaedia Britannica, sweat glands regulate body temperature by secreting water onto the surface of the skin where heat is then removed by evaporation. There are two types of sweat glands found only in mammals, the eccrine sweat glands and the apocrine sweat glands. The eccrine sweat glands are controlled by the sympathetic nervous system and are responsible for regulating body temperature.Full Answer >
Sweat glands are found in the greatest concentration on the palms and soles because the glands keep these surfaces moist, enabling them to provide the most tactile sensation. If the palms and soles are not properly hydrated, the top layer of skin may harden or flake, subsequently reducing sensitivity.Full Answer >
Sweat glands are positioned deep inside the skin, and their primarily function is temperature regulation. The two types of sweat glands are the apocrine and eccrine sweat glands.Full Answer >
The two types of sweat glands are eccrine and apocrine. Eccrine sweat glands are located all over the human body, and apocrine glands are mostly limited to the armpit area.Full Answer >
