Accepted Answer

The interstitial fluid is the largest compartment of extracellular water, accounting for 80% of ECF volume. Plasma is the liquid portion of blood and accounts for only 20-25% of ECF volume. Lymph is a type of extracellular fluid that flows in the lymphatic vessels and drains into the bloodstream. Transcellular fluid is the smallest compartment of ECF and includes fluids in specialized body cavities, such as cerebrospinal fluid, synovial fluid, and aqueous humor.
