Question

1. with hyponatremia, why do cells swell? *

the membrane stops letting water out
the blood has too much salt, so water leaves the cells
the blood has too little salt, so water moves into the cells
the cells make extra water to stay cool

Explanation:

Hyponatremia is a low - sodium condition in the blood. Osmosis causes water to move from an area of lower solute (salt) concentration (blood) to an area of higher solute concentration (inside cells). When blood has too little salt, water moves into cells, causing them to swell.

Answer:

The blood has too little salt, so water moves into the cells
