Answer:
Swelling of the red blood cells occurs.
Explanation:
- <u>Distilled water makes the blood hypotonic ,. that is a less concentrated solution, to the body tissues including the red blood cells. </u>
- Therefore the water will enter the red blood cells and may cause them to lyse or swell.
- <em>Additionally , water will enter the tissue spaces and cause sweling. </em>
- But in the case of a hypertonic solution , ( a salt or saline solution ) , <em>This swelling does not happen because the concentration of the saline will be equal or more than the blood. </em>
- Thus the water will flow only from the blood to the solution. <u>This will not cause swelling.</u>
- But too much of salt is also not recommended.
