Human Lungs black outline icon

About the Human Lungs black outline icon

Two lung lobes curve away from a short vertical trachea at the top, and inside each lobe a tree of thin bronchial branches spreads downward and outward. The drawing communicates breathing, respiratory health and internal anatomy without any clinical clutter. Suitable for hospital department menus, pulmonology clinic sites, health tracking apps, anatomy teaching slides and air quality reports.

The silhouette is nearly symmetrical, with the airway branches angled to fill each lobe evenly and a notch between them at the top. The outline weight stays uniform so the internal branches read as structure, not shading. It pairs with heart, kidney and brain organ icons. Use 32 px or larger to keep the bronchi from filling in.

This is the black outline version of the human lungs icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
