Kidneys win on efficiency

Your lungs filter gases across a surface the size of a studio apartment.
Your kidneys filter blood across a surface the size of a placemat—but with efficiency that would make your lungs jealous.

Why the Difference?

  • Gas exchange requires a massive surface area for efficient oxygen uptake and carbon dioxide release—hence the lung’s sponge-like structure.

  • Glomerular filtration is more selective and pressure-driven, not diffusion-based—so it uses micro-scale sieving rather than massive area.

    This space is for patients, caregivers, and curious minds. We’re glad you’re here.
