SpletThe function of ammonia in eccrine sweat is the excretion of metabolic waste. Bicarbonate – there is about 0.5-5.0mmol/L secreted. There is less concentration of bicarbonate than blood plasma. With HCO 3 being reabsorbed in the sweat duct, there is … Eccrine sweat glands are the major sweat glands of the human body, found in virtually all skin, with the highest density in palm and soles, then on the head, but much less on the torso and the extremities. In other mammals, they are relatively sparse, being found mainly on hairless areas such as foot pads. They reach their peak of development in humans, where they may number 200–400/cm of skin surface. They produce a clear, odorless substance, sweat, consisting primar…
