...M. J. O’Donnell; S. H. P. Maddrell ABSTRACT Because the frontal area of the intercellular clefts in Malpighian tubules is small, and the osmotic permeability of the cell membranes is large, the route for transepithelial water movement during fluid secretion is transcellular. Water movements appear...
