Stretch receptors in the atria are responsible for the secretion of ________.
A) ADH
B) renin
C) aldosterone
D) atrial natriuretic hormone
E) angiotensin
Stretch Receptors
Sensory receptors that sense muscle stretch and contraction, thereby providing feedback to maintain posture and balance.
Atrial Natriuretic Hormone
A hormone secreted by the heart's atria that regulates blood pressure, blood volume, and the balance of fluids and electrolytes in the body.
- Understand the hormonal regulation of renal function, including the interplay between aldosterone, renin, angiotensin II, and atrial natriuretic hormone in controlling blood volume and ion concentration.

Final Answer :
D
Explanation :
Stretch receptors in the atria are responsible for the secretion of atrial natriuretic hormone (ANH) or atrial natriuretic peptide (ANP). This hormone is released in response to stretching of the atrial walls, which typically occurs when there is an increase in blood volume. ANH acts to reduce blood volume and blood pressure by increasing the excretion of sodium and water by the kidneys, among other effects.
