Final answer:
Depression of metabolic tissues and lack of adequate nutrition can cause intracellular edema by decreasing colloid osmotic pressure and causing water to diffuse into cells.
Step-by-step explanation:
Intracellular edema can occur due to depression of metabolic tissues and lack of adequate nutrition to cells. This can lead to a decrease in colloid osmotic pressure (which counterbalances hydrostatic pressure) in capillaries. As a result, water from the blood diffuses passively into the cells, causing them to swell and resulting in intracellular edema.
