Final answer:
Eccrine sweat glands are found all over the skin's surface, especially on the palms, soles, and forehead. They produce a hypotonic sweat for thermoregulation that is mostly water, containing some salt, antibodies, traces of metabolic waste, and dermicidin, an antimicrobial peptide.
Step-by-step explanation:
The location of the eccrine glands is widespread across the skin's surface, with a high density on the palms of the hands, soles of the feet, and forehead. These glands play a crucial role in thermoregulation, meaning they help regulate body temperature. The type of fluid produced by the eccrine glands is a hypotonic sweat, primarily made up of water, with smaller amounts of salt, antibodies, metabolic waste, and dermicidin, an antimicrobial peptide. The correct answer to the student's question is therefore option B: Palms and soles, produce sweat, watery fluid.
An eccrine sweat gland is a type of gland that produces a hypotonic sweat for thermoregulation. These glands are found all over the skin's surface but are especially abundant on the palms of the hand, the soles of the feet, and the forehead. They are coiled glands lying deep in the dermis, with the duct rising up to a pore on the skin surface, where the sweat is released. This type of sweat, released by exocytosis, is hypotonic and composed mostly of water, with some salt, antibodies, traces of metabolic waste, and dermicidin, an antimicrobial peptide.
