Chapter Review. Some organs have a secondary endocrine function. For example, the walls of the atria of the heart produce the hormone atrial natriuretic peptide (ANP), the gastrointestinal tract produces the hormones gastrin, secretin, and cholecystokinin, which aid in digestion, and the kidneys produce erythropoietin (EPO), which stimulates the formation of red blood cells The hormone atrial natriuretic peptide (ANP) is secreted by the walls of the atrial chambers of the heart. The ANP acts to reduce the amount of renin that is produced by the kidney. This then impacts the RAAS system so that less sodium is reclaimed and thus blood volume and blood pressure decrease ADH is a peptide hormone while aldosterone is a steroid hormone. ADH (anti-diuretic hormone) is a neuro-secretary peptide hormone and it prevents the production of dilute urine. On the other hand, Aldosterone is a corticosteroid hormone that stimulates the absorption of sodium by the nephron to regulate water and salt balance Antidiuretic hormone, also known commonly as arginine vasopressin, is a nine amino acid peptide secreted from the posterior pituitary.
