Interstitium is the space between tissue cells where interstitial fluid collects and surrounds cells. This fluid, formed from plasma filtrate, delivers nutrients and removes wastes. Lymph capillaries absorb this fluid through their ends, which are formed by loosely overlapping endothelial cells that act like tiny valves. When interstitial pressure rises, these overlaps open and fluid can enter the lymph capillary. The other terms don’t name the space itself: endothelial cells line vessels, valves in lymph vessels help regulate flow but aren’t the space, and nutrient transport is a broader process. The interstitium specifically designates the tissue-space where uptake into the lymphatic system occurs.
