Correct Option (b) Na+ ions help to retain water in the body
Explanation:
Severe diarrhoea, vomiting, watery stools are the chief symptoms of cholera. All these lead to dehydration. The toxin secreted by Vibrio cholerae causes a continuous activation of adenylate cyclase of intestinal epithelial cells.
The resultant high concentration of cAMP triggers continual secretion of Cl-, HCO3- and water into the lumen of the intestine. Administration of saline not only supports the sodium-potassium pump through which water in cell is restored, but glucose is also symported along with sodium.
