Like sodium cations, chloride anions actively participate in the regulation of the osmolarity of tissue and cells by crossing the cellular membrane and stopping water from entering into a cell or stopping the excessive loss of water from a cell. Chloride anions play an important role in the acid-base balance of an organism since they are involved, along with bicarbonate anions, in the pH buffer system of the body. Another function of chloride ions is in digestive physiology: inside the gastric lumen, hydrochloric acid secreted by stomach cells ionizes into hydrogen and chloride ions, lowering the pH of gastric juiced and allowing enzymatic digestion to take place.
