Intravenous saline injections are often given as treatment for severe dehydration. The concentration of saline (0.9% NaCl) in these injections is the same as that present in human cells. What would happen if pure water was introduced into the body instead of saline?

A. The cells would gain water and swell.
B. The cells would lose water and shrivel.
C. The cells would become impermeable to sodium (Na+) ions.

Final answer:

Pure water introduction leads to cell swelling due to osmosis.


Explanation:

Introducing pure water into the body instead of saline would cause the cells to gain water and swell. This is because pure water is hypotonic, meaning it has a lower concentration of solutes compared to the cell's environment. As a result, water would move into the cells by osmosis, causing them to swell and potentially burst if the imbalance is severe.
