Web55. In the fish gill there are two main types of cells, pavement cells (respiratory cells) and chloride cells (mitochondrial-rich cells). With respect to ionoregulation, what are the primary “roles” of these two cell types? a. Ions are gained across chloride cells and excreted via the pavement cells. b. WebThe gills and kidneys were found to have principal roles in the osmoregulatory processes.
