Question

A person takes a concentrated solution of salt. After sometime he starts vomiting. What is the phenomenon responsible for the situation?

• A. Exocytosis
• B. Endocytosis
• C. Endosmosis
• D. Exosmosis

Answer 1

The correct option is D Exosmosis

When person drinks concentrated salt solution then it eventually reaches to stomach. As salt solution contains more solutes than nearby tissues, then the water from those tissues start moving inner to stomach in the intestine. This process is endosmosis in which the water molecules move from lower solute concentration to higher solute concentration through the stomach wall. The intestine cannot tolerate strain due to extra incoming water and hence, the extra water is spilt out through vomiting.

Thus, the correct answer is option D.
