| Question | Answer |
| How would an Increase in GFR affect Filtration Rate? | LESS Ion REABSORPTION opportunity |
| How would less Ion reabsorption opportunity affect Filtration Rate? | INCREASE Ion LOSS (excretion) |
| How would Decrease in GFR affect Filtration Rate? | MORE Ion REABSORPTION |
| How would more Ion reabsorption opportunity affect Filtration Rate? | LESS Ion excretion = Conserve |
| What are the 2 influences on Tubular Reabsorption? | ANP, Aldosterone |
| Where is ANP secreted from? | Heart |
| What does ANP respond to? | HIGH Na+ |
| What is the function of ANP? | DECREASES active Na+ REABSORPTION --> INCREASE Na+ EXCRETION |
| Where is Aldosterone secreted from? | Adrenal CORTEX |
| What are the function of Aldosterone on Tubular Reabsorption? | ^ Na+ REABSORPTION --> DECREASE Na+ EXCRETION & ^ K+ SECRETION --> ^ K+ EXCRETION |
