Answer:
E. Dilute body fluids and a decrease in the osmolarity of interstitial fluids
Explanation:
When there is excessive water intake into the body, it can lead to water intoxication. It occurs as result of a combination of dilute body fluids and decrease in the osmolarity of interstitial fluids.
When excess water is taken into the body, the extracellular fliuds become very dilute, this results in a decrease in osmolarity , therefore, water will then move into the intracellular fluid by osmosis in order to establish equilibrium.. This causes the cells to swell, and in the brain, this swelling will result in increase in pressure within the cranium. This increase in pressure leads to the symptoms found in water intoxication such as nausea, confusion, and fainting. If not treated, it can result in death.
From the given options;
A. Dilute body fluids is only a part of the cause
B. Osmosis of water from ICF to ECF does not result in water intoxication because in water intoxication, water moves into the ICF from ECF
C. Decrease in water intake is wrong because it is an increase in water intake that results in water intoxication
D. Decrease in the osmolarity of interstitial fluids is only one part of the cause of water intoxication
E. Dilute body fluids and a decrease in the osmolarity of interstitial fluids is the correct option.
