And so chloride ions basically move down their electrochemical gradient from the inside to the outside the cell into the lumen of the small intestine. And so what we see happening is there's a net flow of these sodium chloride ions, sodium chloride salt, and it moves in a general direction to the outside of the cell. And remember, as these salt ions basically move into this direction, what will follow? Well, water molecules will basically follow and water molecules will diffuse across the membrane and follow the net movement of the salt. So we see that the net loss of sodium ions and chloride ions from the cells drives the movement of the water out of the cells and into the lumen of the small intestine. And this leads to the loss of large volumes of water and electrolytes.
