Definition for Eccrine sweat gland
From Biology Forums Dictionary
Eccrine glands (sometimes called merocrine glands) are the major sweat glands of the human body, found in virtually all skin. They produce a clear, odorless substance, consisting primarily of water and NaCl (note that the odor from sweat is due to bacterial activity on the secretions of the apocrine sweat glands). NaCl is reabsorbed in the duct to reduce salt loss. They are active in thermoregulation and emotional sweating (induced by anxiety, fear, stress, and pain).
