Why does edema develop in tissues surrounding a capillary bed experiencing elevated venous pressure?

💡 Explanation

Elevated venous pressure increases capillary hydrostatic pressure, which drives fluid out of the capillaries at a faster rate than it can be reabsorbed; because the filtration rate overwhelms reabsorption and lymphatic drainage, fluid accumulates in the interstitial space, therefore edema results, rather than balanced fluid dynamics.
