Atrial natriuretic factor (ANF), atrial natriuretic peptide (ANP) or atriopeptin, is a polypeptide hormone involved in the homeostatic control of body water,sodium, and adiposity. It is released by atrial myocytes, cells in the atria of the heart, in response to signals of raised blood pressure and acts to reduce the water, sodium and adipose loads on the circulatory system, thereby returning blood pressure to more normal levels.
The answer is D; it INHIBITS the release of renin from the kidneys instead of stimulating the kidneys to release renin.
Renal:
Dilates the afferent glomerular arteriole, constricts the efferent glomerular arteriole, and relaxes the mesangial cells. This increases the glomerular filtration rate, resulting in greater excretion of sodium and water.
Decreases sodium resorption in the renal distal convoluted tubule and cortical collecting duct.
Inhibits renin secretion

it is definitely D
cause by logic this atrial natriuretic peptide will be secreted when there is streching to the heart muscle due to volume overload so the aim of its secretion is to enhance diuresis to return body volume to normal A,B& C will cause this
D it is wrong cause the atrial natriuretric peptide will inhibit the secretion of renin .
take care
