Sweat glands are most quite a few on the soles of the ft. 1. A coil generates an ultra-filtrated fluid. This fluid has the identical sodium concentration (isotonic) because the blood. 2. The fluid travels from the coil up the sweat duct which reabsorbs sodium and chloride (but not potassium). This reabsorption is by way of active transportation (i.e. it requires power from ATP). The Glycogen stored in the sweat glands will only help the reabsorption for less than 10 min., so the power is predominantly provided by the blood. Glucose is the popular power supply, although Lactate and pyruvate will also be used. Fatty acids, ketones, and amino acids are very poorly used. The reabsorption process also acidifies the ultimate sweat. The speed of sweat production depends upon the local skin temperature and core physique temperature. The desk under is predicated on the analysis showing that sweat sodium concentration increases with sweat charge.
