Seven Core Kidney Functions
- Remember the seven core kidney functions: water balance, electrolytes, waste excretion, endocrine roles, erythropoiesis, gluconeogenesis, and blood pressure control.
- For exams, list these succinctly and give one example for each function.
How Kidneys Build The Medullary Gradient
- The concentration gradient arises from the countercurrent multiplier, countercurrent exchanger, and urea handling working together.
- Longer loops of Henle multiply the horizontal gradient and vasa recta preserve it without washing it out.
Three Steps Of Renal Acid Handling
- Describe renal acid handling as three steps: bicarbonate reabsorption, titratable acid excretion, and ammonium production.
- Emphasize ammonium (via glutamine) as the major mechanism allowing large H+ excretion.
