Kidney

Single human kidney shown externally as a classic compact bean-shaped organ in clean anatomical or medical clipart style. The surface is smooth, colored reddish-brown to dark reddish-brown, with a rounded convex lateral border and a distinct concave medial border forming the renal hilum notch. The upper and lower poles are slightly tapered. At the hilum there may be a pale beige or yellowish indentation, often with a short pale ureter stump and small renal vessel stubs or subtle branching vessels emerging from the medial side. No major cutaway is present and internal detail is minimal or absent.
