- Regulation of blood pressure and volume
- Low bp causes kidneys to release renin
- this converts angiotensinogen in angiotensin 1
- converts into angiotensin 2, which acts on adrenal cortex to produce aldosterone
- causes kidneys to reabsorb water and sodium
- causes blood pressure to rise
- blood pressure too high there is an increased blood volume
- heart muscle releases atrial natriuretic hormone
- stops renin secretion
- causes sodium and water to be excreted causing blood pressure to drop
- stops renin secretion
