Question

Quizplus · Accepted Answer

Atrial natriuretic hormone (ANH) is a hormone secreted by the atria of the heart in response to stretching of the atrial wall due to an increase in blood volume. ANH reduces blood volume and pressure by increasing urine volume through its action on the kidneys. ANH inhibits the reabsorption of sodium by the kidneys, thus pulling more water out of the blood, and promoting excretion of excess water and sodium in the urine. Erythropoietin stimulates red blood cell production, aldosterone retains sodium and water, and renin helps regulate blood pressure by activating the renin-angiotensin-aldosterone system.
