I need help with question 17

The ultimate cause of death due to dehydration is a fluid/volume shift that causes structural changes to cells and cellular proteins. Which of the following correcty describes the steps that lead to this lethal fluid/volume shift? 17. A. Esxtracellular osm.pressure increase.s....which leads to an increase in total-body B. A net water loss causes intracellular osm.-press to decrease. Water then moves out of C. A net D. A net water loss causes total-body-water to decrease and extracellular osm-press to water. Water then moves out of cells. cells increases and fluid moves out of cells. increase. Water then moves down its' concentration gradient (out of cells) into the water loss causes extracellular osma-press. to decrease; total-body-water extracellular space. E. None of the above is correct.

Explanation / Answer

17.

A net water loss will decrease the extracellular fluid and hence its osmotic pressure will decrease.

This will create an osmotic pressure gradient between intracellular and extracellular compartments.

So osmotic pressure inside the cells is more compared to extracellular space.

So water will move from cells to extracellular space.

So option C seems correcta.
