5 The Chloride Cell: The Active Transport of Chloride and the Paracellular Pathways

摘要: Publisher Summary This chapter discusses the active transport of chloride and paracellular pathways. The anatomic element directly associated with secretion salts is cell located on gill filaments, mainly its proximal end. These large columnar cells are present in greater quantities seawater-adapted fish less frequent freshwater-adapted fish. tissue lining opercular cavity Fundulus heteroclitus consists a stratified epithelium an underlying layer connective tissue. method utilized for isolation study isolated cell-rich epithelia described chapter. electrical potential difference oscillates between 10 35 mV. flat sheet contains considerable numbers it clear that difference, short-circuit current, ion flux will be related to presence so many cells. Several agents or drugs mechanisms specific effects used interpret membrane phenomena have also tested their action fluxes. In all instances, either stimulations inhibitions were correlated increase by studied.
