Nephrons

• Nephrons


  nephrons r the structural + functional units of the kidneys

  each kidney contains appox 1 mill nephrons acting in parralel to make urine

  each nephron creates a cell + protein free filtrate from blood

  from that filtrate, it recovers chems the body needs while also secreting into that filtrate selected chems that the body needs to get rid of
• Collecting Ducts


  nearby nephrons empty their processed filtrate into one of the thousands of collecting ducts, which convey this fluid, now urine, into the renal pelvis
• Renal Corpuscle


  each renal corpuscle consists of a tuft of capillaries = glomerulus + a hollow cupped structure = glomerular capsule

  the glomerular capsule is continous w its renal tubule + completely surrounds the glomerulus
