Eccrine sweat glands (.
Eccrine glands are composed of an intraepidermal spiral duct, the "acrosyringium"; a dermal duct, consisting of a straight and coiled portion; and a secretory tubule, coiled deep in the
Eccrine glands are active in thermoregulation by providing cooling from water evaporation of sweat secreted by the glands on the body surface and emotionally induced sweating (anxiety, fear, stress, and pain).[6][7] The white sediment in otherwise colorless eccrine secretions is caused by evaporation that increases the concentration of salts.
The odor from sweat is due to bacterial activity on the secretions of the
Secretion
The secretion of eccrine glands is a sterile, dilute
Relative to the plasma and extracellular fluid, the concentration of Na+ ions is much lower in sweat (~40 mM in sweat versus ~140 mM in plasma and extracellular fluid). Initially, within the eccrine glands, sweat has a high concentration of Na+ ions. The Na+ ions are re-absorbed into the tissue via the
