What causes diarrhea?
Damage to epithelial cells lining small intestine, loss of mircrovilli due to toxins, excess secretion of water(by cholera toxins)
1 of 8
Why doesn't water work in rehydrating?
It isn't being absorbed from small intestine-cells are losing water, doesn't contain ions lost from cellsq
2 of 8
What does ORS contain?
Salt (sodium and chloride ions), sugars (glucose and sucrose), water, potassium
3 of 8
Function of water in ORS?
rehydrates tissues
4 of 8
Function of sodium in ORS?
Increase glucose absorption as sodium and glucose are co transported through sodium-glucose carrier protiens and it replaces sodium ions lost from cells
5 of 8
Function of glucose in ORS?
provides energy and stimulate sodium uptake from intestine
6 of 8
Function of potassium in ORS?
Replace lost potassium ions and stimulate appetite
7 of 8
How is ORS well suited to poorer countries?
Cheap and easy to administer
