About the Kidney black outline icon
Two mirrored kidney shapes with their inner notches facing each other, joined by a pair of ureter tubes that run straight down the center. The drawing reads instantly as the renal system, useful in anatomy diagrams, urology and nephrology clinic sites, dialysis service pages, medical school slide decks and patient education leaflets or health tracking apps.
Both organs sit at equal height with a symmetrical bean silhouette, and the ureters stay parallel so the pair balances on the baseline. Use it alongside heart, lung and liver icons in the organ set; at small sizes the tubes can merge, so 32 px or larger works best.
This is the black outline version of the kidney icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
