Answer:
(A) - The volume of the blood plasma increases on overhydration and decreaes on dehydration.
(B) - Osmolality of blood increases with the dehydration and decreases with the overhydration.
Explanation:
If the levels of drinking water is increased, then the plasma becomes more dilute and the plasma volume increases because <u>the water will be reabsorbed more and which as a result reduces plasma concentration of the solutes and increases volume of plasma.</u>
Plasma osmolality measures electrolyte-water balance of the body. <u>As mentioned, above on overhydration, the plasma concentration of the solutes decraeses which also decreases osmolality. So, Osmolality of blood increases with the dehydration and decreases with the overhydration. </u>Increased osmolality in blood stimulate the secretion of antidiuretic hormone which results in the increased water reabsorption and therefore, more concentrated urine and hence blood plasma with less concentration.
