$A$ person takes a concentrated solution of salt; after some time,he starts vomiting. What is the phenomenon responsible for this situation? Explain.

(N/A) The phenomenon responsible for this situation is $Exosmosis$. When a person consumes a concentrated salt solution (a hypertonic solution),the concentration of salt outside the cells of the alimentary canal becomes much higher than inside the cells. Due to the difference in concentration,water moves out of the cells into the surrounding medium through the process of $Exosmosis$. This leads to severe dehydration of the cells lining the digestive tract,which triggers the body's protective reflex to expel the irritant,resulting in vomiting.
