GENERAL HISTOLOGY

Detailed explanation-1: -Pure water is never used for the purpose: Saline water is isotonic to the cells in the body. Pure water is hypotonic to the cells in the body. The cells when placed in a hypotonic solution will swell up due to the influx of water inside the cells and will ultimately burst.

Detailed explanation-2: -Osmosis is the movement of water from a dilute environment to a more concentrated one. So, pure water injected into an IV would diffuse via osmosis into the more concentrated environment inside red blood cells, make them swell up because of the excess water and eventually make them burst.

Detailed explanation-3: -If a cell encounters a hypotonic environment, (like pure water for instance), water will diffuse into the cell and the cell will begin to swell. This can of course lead to an explosion of sorts.

Detailed explanation-4: -Answer and Explanation: If you place a blood cell in a beaker filled with pure water, the cell would likely burst. Pure water is a hypotonic solution compared to a cell. This means that the external environment has a greater concentration of water compared to inside the cell.

Detailed explanation-5: -This is called osmosis. The sea water is far more concentrated than our body cells. So if one drinks sea water, his cells will rapidly lose water as our body cell is also a semipermeable membrane and as a result it allow water to go out of the cells. This will cause dehydration and the cells will shrink.
