- Function of Na+ ions in saline drip
Does Na+ions prevent water loss from body?
Sorry, but I still don't understand how does Na+ help in preventing water loss from body.Human body is big bag of saline solution. But diarrhea causes fluid and salt loss and human enzymes need minimum salt level. Normally the saline has some glucose to speed absorption. Some of the food poisoning (diarrhea) bacteria interfere with chloride metabolism. Although Sodium is the highest concentration electrolyte, Potassium is required by heart and nervous system.
Are you confusing with NaCl? Remember the ratio of ions is 1:1 the idea is to keep salt in the body not prevent water loss. Na+ ions can be useful to maintain cell membrane permeability among other things.Sorry, but I still don't understand how does Na+ help in preventing water loss from body.
Thank You.In cholera, it is not too effective to give water alone to rehydrate (sodium and glucose are also important), because factors have to be supplied that enable the body to take up the water. Historically, many people came across the correct solution, but understanding why had to wait for the discovery of the sodium-glucose symporter mechanism.
