Verified step by step guidance

Step 1: Understand the function of atrial natriuretic peptide (ANP). ANP is a hormone that helps regulate blood pressure and fluid balance by promoting sodium excretion and reducing blood volume.

Step 2: Identify the organ responsible for synthesizing ANP. ANP is produced by specialized cells in the atria of the heart in response to increased blood volume or pressure.

Step 3: Eliminate the other options based on their functions. The liver synthesizes proteins like albumin and clotting factors, the pancreas produces insulin and digestive enzymes, and the kidney regulates fluid balance and produces hormones like erythropoietin.

Step 4: Confirm that the heart is the correct answer because it contains atrial myocytes, which release ANP when stretched due to increased blood volume.

Step 5: Conclude that the heart is the organ responsible for synthesizing atrial natriuretic peptide (ANP).
