Differentiate between the 3 classes of kidney
failure, matching each with the most likely cause

• Pre-Renal
• Intra Renal
• Post Renal

In terms of the process of urine formation,
explain the differences between the possible
causes of kidney failure.

Pre-renal

• Heart attack can lead to loss of blood flow to
  the kidneys.
• Poor blood flow means decreased glomerular
  filtration and may lead to atrophy.

Myocardial Infarction!
6
Intra-renal

• Bacterial infection of the kidneys occurs after
  pharyngitis caused by the Streptococcus bacteria.
• Glomerulonephritis results from infection.
• Glomerular function is disrupted and correct
  filtration no longer occurs.

Streptococcus Pharyngitis!
7
Post-renal

• A blockage in the ureter causes hydronephrosis
  (fluid buildup in the renal pelvis and calices).
• The pressure from this causes nephron damage and
  kidney failure.

Blood before dam water is Urine after dam

• An energy producing dam is blocked by a fallen
  tree up river (pre-renal). Now the dam is not
  producing energy
• An angry environmentalist toys with the turbines
  within the dam (intra-renal). The dam is unable
  to produce energy.
• An earthquake causes a landslide blocking the
  river after the dam
• (post-renal). This creates back pressure,
  damaging the dam.

• Kidneys must be functioning for homeostasis.
