Where salt goes, water follows, thereby re-hydrating this important liquid layer of the lungs. This layer of lubricating mucus traps irritants and pathogens, which can later be expelled by coughing., as opposed to thin and runny mucus, and this can plug up passageways in the lungs.found In experiments, increasing the abundance of ionocytes increased liquid absorption, not liquid secretion."These findings indicate that ionocytes mediate liquid absorption, and secretory cells mediate liquid secretion,""Moreover, the divergent role of CFTR in ionocytes and secretory cells suggests that cystic fibrosis disrupts both liquid secretion and absorption."
