Thus, sodium and water are reabsorbed from the sweat gland tissues into the body. However, failure of the chloride channel to reabsorb chloride leads to a loss of sodium onto the skin surface and a subsequent fluid loss ... WebThe channel is usually involved in secreting chloride and bicarbonate ions at hyperpolarized potentials, so it contains fixed positive charges that allow a capture of anions from the cytoplasm by electrostatic attraction (9). At the center of the pore lies a positive charge, which allows for attraction of anions (9).
