Electrolytes * Important for their chemical, physical (osmotic), and electrical effects on the body * Common disruption due to * sweating * Diarrhea * Vomiting * Hormone imbalance * Kidney disorders Electrolytes in Sweating * Heat control * Two types * Eccrine - the most numerous type that are found all over the body, particularly on the palms of the hands, soles of the feet and forehead * Apocrine - mostly confined to the armpits ( axilla ) and the anal-genital area. They typically end in hair follicles rather than pores. * Compared to apocrine glands, eccrine glands: * are smaller * are active from birth (Apocrine glands become active only at puberty) * produce a sweat that is free of proteins and fatty acids * Loss of Na + , Cl - , H 2 O Electrolytes in Sweating * the sweat from apocrine glands also contains proteins and fatty acids, which make it thicker and give it a milkier or yellowish color. * This is why underarm stains in clothing appear yellowish.

Unformatted text preview: * Sweat itself has no odor, but when bacteria on the skin and hair metabolize the proteins and fatty acids, they produce an unpleasant odor. * This is why deodorants and anti-perspirants are applied to the underarms instead of the whole body. * The maximum volume of sweat that a person who is not adapted to a hot climate can produce is about one liter per hour. * Amazingly, if you move to a hot climate such as the American desert southwest or the tropics, your ability to produce sweat will increase to about two to three liters per hour within about six weeks! This appears to be the maximum amount that you can produce. Electrolyte Measurement * Effects depend on * Concentration * Charge * Equivalent (Eq)- the amount of electrolyte that would neutralize 1 mole of hydrogen inos (H + ) or hydroxide ions (OH-)...
