Elevated blood pressure under resting conditions results in increased urinary output because

A) baroreceptors signal the hypothalamus to increase ADH secretion.
B) elevated blood pressure stimulates renin secretion.
C) the amount of angiotensin II formed is increased.
D) aldosterone levels increase.
E) baroreceptors signal the hypothalamus to decrease ADH secretion.

Baroreceptors

Sensory nerve endings present in the walls of blood vessels and the heart that detect changes in blood pressure and help regulate it.

ADH Secretion

The release of Antidiuretic Hormone, which helps regulate water balance in the body by increasing water reabsorption in the kidneys.

Elevated Blood Pressure

A condition characterized by higher than normal pressure exerted by circulating blood against the walls of the arteries, also known as hypertension.

  • Elucidate the contribution of ADH to fluid homeostasis and its influence on vascular pressure and volume.

Final Answer :
E
Explanation :
Elevated blood pressure under resting conditions leads to increased urinary output primarily because baroreceptors, which sense changes in blood pressure, signal the hypothalamus to decrease the secretion of antidiuretic hormone (ADH). ADH works to conserve water in the body by reducing water loss in urine. When its secretion is decreased in response to high blood pressure, more water is excreted, leading to increased urinary output.
