What happens when a person becomes dehydrated
A
Interstitial fluid becomes low
B
Interstitial fluid becomes too high
C
the blood cells begin to rupture
D
A shift in tonicity occurs
Explanation: 

Detailed explanation-1: -In dehydration, fluid from the extracellular compartment is depleted first, followed by fluid from the intracellular space. Fluid loss from the intracellular space results in cellular shrinkage and metabolic dysfunction.

Detailed explanation-2: -Moderate to severe dehydration can cause tiredness, confusion, muscle cramping, poor kidney function, little-to-no urine production, and fast heart rate. Severe dehydration can lead to shock, weak pulse, bluish skin, very low blood pressure, lack of urine production, and in extreme cases, death.

Detailed explanation-3: -Dehydration occurs when your body loses more fluid than you take in. When the normal water content of your body is reduced, it upsets the balance of minerals (salts and sugar) in your body, which affects the way it functions.

Detailed explanation-4: -The main effect of inadequate ECF volume is to reduce plasma volume and thus to compromise cardiovascular function, in extreme cases by causing circulatory shock.
