  • Kidney Function
    • Ultrafiltration
      • a high pressure is built up which squeezes water, urea, ions and sugar out of the blood.
        • Goes into the Bowman's capsule
          • The membranes between the blood vessels and the Bowmans capsule act like filters
            • This allows big molecules like proteins and blood cells to stay in the blood
    • Nephrons are filtration units in the kidney's
      • Ultrafiltration
        • a high pressure is built up which squeezes water, urea, ions and sugar out of the blood.
          • Goes into the Bowman's capsule
            • The membranes between the blood vessels and the Bowmans capsule act like filters
              • This allows big molecules like proteins and blood cells to stay in the blood
      • Blood enters the capillary network from the renal artery
        • The blood is filtered and products are squeezed into the capsule
          • These products are then made into either useful or wasted substances.
            • Useful subsatnaces are re-absorbed into the blood and wasted substances are turned to urea
    • Reabsorbtion
      • as the liquid flows along the nephron useful substances are reabsorbed into the blood
        • all the sugar is reabsorbed
        • sufficient ions are reabsorbed
        • Sufficient water is reabsorbed
    • Release of waste
      • The remaining substances continue along the nephron and into the bladder as urine
