Explain how and why drinking water affects:<br> (A) Blood plasma<br> (B) Blood plasma osmolarity
Oxana [17]

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.

What is the difference between a pandemic and an endemic
Vladimir [108]
A pandemic is all over the world meaning the whole world is affected not just in one country
A endemic is in a country or community rather then the entire world just in parts

The difference is a endemic is smaller it could turn in to a pandemic though

But a pandemic is the whole of it the entire earth.
