<P> Atrial natriuretic peptide ( ANP ) is a peptide hormone which reduces an expanded extracellular fluid ( ECF ) volume by increasing renal sodium excretion . ANP is synthesized , and secreted by cardiac muscle cells in the walls of the atria in the heart . These cells contain volume receptors which respond to increased stretching of the atrial wall due to increased atrial blood volume . ANP is one of a family of nine natriuretic peptides : seven are atrial in origin . </P>
