Which of the following is a direct result of antidiuretic hormone?

A.

Increased urine acidity

B.

Increased urine volume

C.

Increased urine salinity

D.

Decreased urine volume

Answer and Explanation

The Correct Answer is D

A. Increased urine acidity: Antidiuretic hormone (ADH) primarily affects water reabsorption in the kidneys, not urine acidity. It does not have a direct effect on the acidity of the urine.

B. Increased urine volume: ADH works to conserve water by increasing water reabsorption in the kidneys, which decreases urine volume.

C. Increased urine salinity: While ADH does increase water reabsorption, which could concentrate the urine, its direct action is on water retention, not specifically on increasing urine salinity.

D. Decreased urine volume: ADH promotes water reabsorption in the kidneys, leading to decreased urine output. This is the direct and correct result of ADH action.

Correct Answer is B

Explanation

A. It stimulates angiotensin II secretion: Antidiuretic hormone (ADH) does not directly stimulate angiotensin II secretion; instead, it acts on the kidneys to promote water reabsorption.

B. It promotes water conservation: ADH promotes water conservation by increasing water reabsorption in the kidneys, reducing urine output, and thus helping to maintain fluid balance.

C. It inhibits salivation and thirst: ADH does not inhibit salivation or thirst; in fact, it can increase thirst to encourage fluid intake when dehydration is detected.

D. It stimulates hypothalamic osmoreceptors: While ADH affects hypothalamic osmoreceptors indirectly by promoting water retention, its primary function is to act on the kidneys to conserve water.

Correct Answer is C

Explanation

A. Extracellular fluid (ECF) includes all the fluid outside of cells, such as interstitial fluid, blood plasma, and lymph. However, the majority of body water is found inside the cells.

B. Blood plasma and lymph are components of the extracellular fluid. Although they contain water, they do not hold the greatest volume compared to intracellular fluid.

C. Intracellular fluid (ICF) refers to the fluid within the cells, and it constitutes the largest volume of water in the body.

D. Tissue (interstitial) fluid is part of the extracellular fluid found between cells. While it contains a significant amount of water, it does not account for the greatest volume in the body.
