Question

What stimulates ANP?

Answer 1

ANP or Atrial Natriuretic Peptide:

1. Atrial natriuretic peptide (ANP) is a cardiac hormone that is composed of 28 amino acids.
2. ANP is synthesized and released by the heart.
3. ANP hormone acts as a vasodilator which increases renal blood flow.
4. ANP also reduces the tubular reabsorption of sodium.
5. These two actions result in increased urinary elimination of salt and water.
6. An abnormal increase in blood volume level and blood sodium level stimulates the secretion of ANP.
