If a person’s blood cortisol concentration is 10 µg/mL, and 10 mg of cortisol can be excreted from the body in a 24-hour period,
RSB [31]

Answer:

1000 ml of blood plasma was “cleared”

Explanation:

Given,

Concentration of a person’s blood cortisol = 10µg/mL

The amount of cortisol excreted from the body in a period of 24 hour = 10mg

The volume of blood plasma cleared during this time period is equal to

amount of cortisol excreted from the body divided by Concentration of a person’s blood cortisol

The above definition could be represented as following-

volume of blood plasma cleared  = \frac{A}{B} \\

Where A represents amount of cortisol excreted from the body

while B represents the concentration of a person’s blood cortisol

Substituting the given values in above equation, we get -

= \frac{10 * 10^{-3}g}{10*10^{-6}\frac{g}{ml} } \\= 1000 ml

1000 ml of blood plasma was “cleared”
