← Human Body & HealthWhich outcome occurs when interstitial fluid hydrostatic pressure exceeds the oncotic pressure gradient in leg tissues?
A)Increased lymphatic vessel contraction rate
B)Reduced capillary fluid reabsorption
C)Elevated erythrocyte sedimentation rate
D)Peripheral edema within the lower extremities✓
💡 Explanation
Edema results from fluid accumulation in interstitial spaces. Because the interstitial fluid hydrostatic pressure overwhelms the oncotic pressure, fluid moves out of capillaries faster than it can be reabsorbed or drained by lymphatics; therefore, edema occurs rather than normal fluid balance.
