Human heart glowing effects with blood circulation from the heart. The heart s surface is a intricate mosaic of veins and arteries, each one glowing faintly, as if lit from within by the fire of life itself. From its core, rivers of shimmering blood flow outward, branching into a vast, glowing network that stretches into the infinite horizon. These luminous streams twist and spiral like liquid light, weaving through the air in a hypnotic dance of vitality and motion. The blood carries with it a faint, golden sparkle, leaving behind trails of stardust that drift lazily in the dream-laden atmosphere.
