← Human Body & HealthWhich mechanism explains why localized edema develops after a surgical incision disrupts lymphatic vessels?
A)Increased oncotic pressure draws fluid
B)Impaired lymphatic drainage raises pressure✓
C)Capillary hydrostatic pressure decreases fluid
D)Systemic vasoconstriction reduces blood flow
💡 Explanation
Localized edema occurs because lymphatic vessel disruption impairs lymphatic drainage, raising interstitial hydrostatic pressure. This increased pressure opposes capillary reabsorption, therefore fluid accumulates in the interstitial space, rather than being cleared by the lymphatic system or reabsorbed into capillaries.
