atrial natriuretic peptide
(noun)
a strong vasodilatory, peptide hormone, secreted by the cardiac muscle cells
Examples of atrial natriuretic peptide in the following topics:
-
Other Hormonal Controls for Osmoregulation
- The atrial natriuretic peptide (ANP) hormone lowers blood pressure by acting as a vasodilator (dilating or widening blood vessels).
-
Organs with Secondary Endocrine Functions
- These cells release the hormone atrial natriuretic peptide (ANP) in response to increased blood volume .
- The hormone atrial natriuretic peptide (ANP), released in response to increased blood volume, is produced by endocrine cells in the heart.
-
Other Hormone-Producing Structures
- Atrial natriuretic hormone (ANH), or atriopeptin, is a powerful vasodilator, and a protein (polypeptide) hormone secreted by heart muscle cells.
- It is released by muscle cells in the upper chambers (atria) of the heart (atrial myocytes) in response to high blood pressure.
- Gastric inhibitory peptide (GIP) - is in the duodenum and decreases the stomach churning in turn slowing the emptying in the stomach.
-
Water Content in the Body
- Body water is regulated by hormones, including anti-diuretic hormone (ADH), aldosterone and a trial natriuretic peptide.
-
Pulmonary Edema
- B-type natriuretic peptide (BNP) is available in many hospitals, sometimes even as a point-of-care test.
-
Sodium Balance Regulation
- Atrial peptide also causes loss of sodium by the kidneys: it is secreted from the heart in high sodium states due either to excess intake or cardiac disease.
