Detailed explanation-1: -The interstitial space that lies between blood vessels and cells provides the fluid and structural environment surrounding those cells. Under most conditions in most tissues, fluid from the vascular space continually filters from the microvessels into the interstitial space and is not reabsorbed (1).

Detailed explanation-2: -The interstitial space is the area between cells, which is typically composed of fluid and proteins (such as collagen and/or proteoglycans).
