प्रश्न
A person takes concentrated solution of salt, after sometime, he starts vomiting. What is the phenomenon responsible for such situation? Explain.
उत्तर
The phenomenon responsible for such a situation is exosmosis. A concentrated solution of salt is hypertonic to the cells of our body i.e., the concentration of water molecules in it is lesser than the concentration of water molecules in the cells of our 6ody. When a person drinks concentrated salt solution, water comes out of the cells of the alimentary canal (stomach, intestine, etc.) by the process of exosmosis causing a loss of water in the cells. This results in dehydration, diarrhoea and vomiting.
