ANF – Atrial natriuretic factor is called the hormones of the heart.

ANF – Atrial natriuretic factor is called the hormones of the heart. It is a protein-based hormone, secreted and released by the cardiac muscle cells. The synthesized hormones are released into the atrium in counter to the high blood pressure through the heart muscle cells. The ANF – Atrial natriuretic factor is also called ANP – Atrial natriuretic peptide or ANH – Atrial natriuretic hormone or Atriopeptin. ANF is an important vasodilator, which is involved in the homeostatic regulation of body fluids, sodium, potassium and fats in the adipose tissue.

The ANF is synthesized as inactive peptide hormones and is encoded by the human NPPA- natriuretic peptide A, a gene located on the short arm of  chromosome  1. The ANF is secreted and produced in response to:

Atrial natriuretic factor acts on various organs of the  human body  and is mainly involved in the following physiological effects.
