Detailed Solution

The heart secretes atrial natriuretic peptide (ANP), which lowers blood pressure by dilating blood vessels. The kidneys release hormones such as renin, angiotensin, and erythropoietin (EPO). Renin and angiotensin regulate blood pressure, while EPO stimulates the production of red blood cells.

Hormones of the Heart

Atrial Natriuretic Peptide (ANP): A hormone released by the atrial walls of the heart. It helps reduce blood pressure by dilating blood vessels and promoting the kidneys to excrete more sodium and water.

Hormones of the Kidneys

Renin: An enzyme that triggers the formation of angiotensin, playing a key role in blood pressure regulation and stimulating aldosterone release.
Angiotensin: Works with renin to maintain blood pressure and promotes the secretion of aldosterone.
Erythropoietin (EPO): A hormone that stimulates bone marrow to increase red blood cell production.
1,25-dihydroxyvitamin D₃ (Calcitriol): The active form of vitamin D produced in the kidneys, essential for regulating calcium and phosphate balance.
