← Human Body & HealthIf interstitial hydrostatic pressure significantly rises due to impaired lymphatic drainage after lower limb trauma, which consequence is most likely?
A)Increased plasma protein concentration
B)Reduced capillary fluid reabsorption✓
C)Elevated systemic blood pressure
D)Enhanced red blood cell production
💡 Explanation
Elevated interstitial hydrostatic pressure opposes the inward osmotic pressure gradient at capillaries, thereby reducing fluid reabsorption via the Starling forces. This occurs because increased pressure in the interstitial space directly counteracts the osmotic pull of proteins in the blood; therefore, net fluid movement into the capillaries decreases, rather than being reabsorbed effectively.
