| Question | Answer |
|---|---|
| source of ADH | posterior pituitary gland |
| source of aldosterone | adrenal cortex |
| source of ANH | hearts atrial wall |
| source of renin | kidneys |
| source of EPO | kidneys |
| trigger of ADH | Dehydration / high osmolarity |
| trigger of aldosterone | Low BP / low Na+ / RAAS |
| trigger of ANH | HIGH blood pressure |
| trigger of renin | Low BP |
| trigger of EPO | Low blood oxygen |
| kidney action of ADH | ↑ water reabsorption in collecting ducts |
| kidney action of aldosterone | ↑ Na+ reabsorption → water follows |
| kidney action of ANH | ↑ Na+ secretion → water follows into urine |
| kidney action of renin | Activates RAAS → angiotensin → aldosterone → ↑ BP |
| kidney action of EPO | → bone marrow → more RBCs produced |
| ADH effect of urine output | ↓ LESS (concentrated) |
| aldosterone effect of urine output | ↓ LESS |
| ANH effect of urine output | ↑ MORE |
| renin effect of urine output | ↓ LESS (indirectly) |
| EPO effect of urine output | N/A |
