7.7 Kidney diseases

1) Diabetes Mellitus:

  • Caused by inadequate secretion of insulin from islet vells in the pancreas
  • Blood sugar levels rise.
  • Excess sugar remains in the nephron, it is not filtered back into the circulatory system.
  • People with this will often urinate a large amount of water because the sugar causes osmotic pressure. This will have to be replenished.
  • Type 2 diabetes.

2) Diabetes Insipidus:

  • Caused by destruction of ADH producing cells or nerve tracts between the hypothalamus and pituitary gland. Without ADH, all 20mL per minute will be urinated and will create a large thirst responce.
  • Type 1 Diabetes.

3) Bright's Disease:

  • AKA- Nephrititis
  • many diseases characterized by inflammation of the nephrons.
  • Filtration system doesn't work properly and allows proteins to stay in the kidney which causes them to swell with water because there is no mechanism to remove proteins from the kidney.
  • Increases output of urine.

4) Kidney Stones:

  • Caused by the percipitation of mineral solutes from the blood.
  • Two groups: Alkaline and acid stones.
  • These stones can tear delicate tissues as they move toward the bladder.
  • can lodge in the urethra and cause alot of pain trying to pass these stones.





Dialysis technology

  • People that cant properly filter their blood with the use of their own kidneys can use technology to mechanicly filter out impurities and toxins from their blood.
