What is the functional unit of the kidney?
Nephron
What are the functions of the kidneys? Which is the primary function?
- Filtration of blood (primary)
- Create urine
- Rid the body of waste in the form of urine: urea, bacterial toxins, water-soluble drugs, drug metabolites
- Excrete or conserve fluid
- Keep electrolytes balance
- Acid-base balance
- Activate vitamin D
- Produce erythropoietin
- Produce renin (for RAAS)
- Regulates blood pressure
What is the normal blood pH?
7.35 - 7.45
What organ regulates the Renin-Angiotensin-Aldosterone System?
- Kidneys
- The kidneys will release renin to activate RAAS
What conditions would cause the kidneys to activate the Renin-Angiotensin-Aldosterone System?
- Decreased blood flow to the kidneys (decreased renal perfusion/renal ischemia)
- Decreased arterial blood pressure (i.e. hypotension)
- Decreased blood volume
- Decreased serum sodium (hyponatremia)
- Increased urine sodium
What is the purpose of the Renin-Angiotensin-Aldosterone System?
- To retain sodium, thus retaining fluid
- Increasing blood volume & increasing blood pressure
- Increasing serum sodium levels
- Increase renal perfusion
What are the steps of the Renin-Angiotensin-Aldosterone System?
- Kidneys release Renin
- Renin meets up with Angiotensinogen (which comes from the liver)
- Chemical reaction occurs between Renin & Angiotensinogen –> Angiotensin I is created
- Angiotensin Converting Enzyme (which comes from the lungs) converts Angiotensin I to Angiotensin II
- Angiotensin II promotes vasoconstriction of the arteries/arterioles
- Angiotensin II acts on the adrenal cortex, releasing aldosterone
- Aldosterone acts on the kidneys to retain sodium
- Retention of sodium causes fluid to be retained & potassium to be excreted
- Blood volume increases, blood pressure increases, renal perfusion increases, serum sodium levels increases
- When blood pressure is an appropriate level, the kidneys will stop releasing Renin and will stop RAAS
