FIGURE 6-11 Formation and cardiovascular/renal actions of atrial natriuretic peptide (ANP). ANP, which is released from cardiac atrial tissue in response to atrial distension, sympathetic stimulation, increased angiotensin II, and en-dothelin, functions as a counter-regulatory mechanism for the renin-angiotensin-aldosterone system. ANP decreases renin release, angiotensin II and aldosterone formation, blood volume, central venous pressure, and arterial pressure. NEP, neutral endopeptidase; GFR, glomerular filtration rate; CVP, central venous pressure; CO, cardiac output; SVR, systemic vascular resistance.
