SUMMARY
1. Stimuli: hypotension, volume depletion, increased sympathetic activity.
2. Receptors detecting change in ECF volume: baroreceptors or stretch receptors in the wall of the afferent arteriole, cardiac and arterial receptors, cells of macula densa in early distal tubule (stimulated by decrease in chloride).
3. Acute: renin released from granules.
4. Chronic stimuli: increased synthesis of pro-renin.
5. Renin levels increase with ACE-I and A-II receptor blockers.
