A person takes concentrated solution of salt, after sometime, he starts vomiting. What is the phenomenon responsible for such situation? Explain.


Concentrated salt solution is a hypertonic solution which causes dehydration in the alimentary canal* due to exosmosis*. This causes stretching and hence vomiting.

*Exosmosis:
The passage of a fluid through a semipermeable membrane from high concentration solution to a lower concentration.
*Alimentary canal: The whole passage through which the food passes through the body from the mouth to the anus.
