← Human Body & HealthAn engineer designs a wearable compression device to enhance lymphatic drainage in a patient with chronic edema. If the device applies excessive external pressure, which consequence follows?
A)Increased capillary oncotic pressure
B)Reduced net capillary filtration✓
C)Increased interstitial protein concentration
D)Enhanced interstitial fluid production
💡 Explanation
Excessive external pressure compresses capillaries, opposing hydrostatic pressure and diminishing fluid outflow, because net capillary filtration is determined by the balance of hydrostatic and oncotic pressures. Therefore, overall fluid movement from capillaries decreases, rather than increasing interstitial protein or fluid production.
