What is the mathematical expression for urinary excretion rate?
What is the mathematical expression for urinary excretion rate?
- Filtration rate + Reabsorption rate + Secretion rate
- Filtration rate - Reabsorption rate - Secretion rate
- Filtration rate * Reabsorption rate / Secretion rate
- Filtration rate - Reabsorption rate + Secretion rate (correct)
