What is the result of any process that increases interstitial fluid pressure?

• A. Decreased lymphatic flow
• B. Edema
• C. Increased vascular resistance
• D. Fluid resorption

Answer: (B)

The result of any process that increases interstitial fluid pressure predominantly leads to edema. Edema occurs when excess fluid accumulates in the interstitial spaces, which can be triggered by an increase in interstitial pressure. This accumulation disrupts the normal balance between fluid filtration from the capillaries and fluid reabsorption, causing more fluid to be retained in the tissues.

When interstitial fluid pressure rises, it can hamper the outflow of lymphatic fluid, contributing to further fluid retention and edema development. This process illustrates how increased pressure in the interstitial spaces disrupts homeostasis and leads to pathological conditions such as swelling in the affected tissues.
