Which of the following regulatory mechanisms would be stimulated as a result of the increased osmolality that results from a Na+ level of 152 mEq/L?
A) Increased urine output
B) An increased release of ADH
C) An increase in renin production
D) An increase in the secretion of aldosterone
E) A decreased release of ADH
Osmolality
A measure of the number of solute particles in a kilogram of solvent, reflecting the concentration of solutes in a fluid.
ADH Release
Antidiuretic hormone (ADH) release is a process triggered by the hypothalamus that instructs the pituitary gland to release ADH into the bloodstream, which helps control the balance of water in the body.
- Explain the function and control of Antidiuretic Hormone (ADH) in the context of urine formation and the preservation of body water.
- Comprehend the principle of osmolality and its influence on the transfer of water across compartments.

Final Answer :
B
Explanation :
An increased Na+ level leads to increased osmolality, which stimulates the release of Antidiuretic Hormone (ADH) to promote water reabsorption and dilute the blood osmolality.
