The Nephrons: Tiny Filters With a Big Job

  1. Each kidney has about a million nephrons—microscopic filters with massive impact.
  2. A nephron filters blood, reclaims nutrients, and forms urine.
  3. The glomerulus acts like a fine sieve, catching waste but keeping proteins.
  4. The tubules adjust water, salt, and pH before sending urine out.
  5. Nephrons work continuously, filtering plasma every 45 minutes.
  6. They’re so efficient that most water and nutrients are reabsorbed.
  7. Each nephron operates independently yet synchronizes with millions of others.
  8. Damage to nephrons can silently lead to kidney disease.
  9. These microscopic structures process around 180 liters of fluid daily.
  10. Tiny but mighty, nephrons are the foundation of life’s filtration system.
