Which of the following primarily serve to prevent leakage of water and solutes between epithelial cells?

Tight junctions are one of the three types of cell junctions that bind epithelial cells. The plasma membranes of adjacent cells are tightly pressed against each other and are bound together by specific proteins. Tight junctions between epithelial cells mainly serve to prevent leakage of water and solutes between epithelial cells. For example, they prevent leakage of water into the surrounding cells in our sweat glands, making our skin watertight.
