Renal interstitial fluid

A pale translucent region representing renal interstitial extracellular fluid, shown as a soft amorphous patch, pooled shape, droplet-like compartment, or diffuse background field with smooth or irregular rounded edges and no membrane. It appears lightly tinted and watery, in very pale yellow, straw-yellow, amber, pink, beige, or light blue, with subtle shading or highlights. The space is smooth, mostly featureless, and cell-free, suitable for labeling as the fluid surrounding renal tubules outside renal epithelial cells in renal transport diagrams. It may include a few scattered dissolved ion symbols when needed, but no solid internal structures.
