About ________ of cardiac output is supplied to the kidneys for osmoregulation and excretion.
- Correct answerA$\dfrac{1}{5}$ th
- B$\dfrac{1}{6}$ th
- C$\dfrac{1}{4}$ th
- D$\dfrac{1}{8}$ th
Solution
On an average, $1100-1200$ ml of blood is filtered by the kidneys per minute.
This volume constitutes roughly $\dfrac{1}{5}$th of the blood pumped out by each ventricle of the heart in a minute, which is the cardiac output.
Therefore, about $\dfrac{1}{5}$th of the cardiac output is supplied to the kidneys for osmoregulation and excretion.
Answer: $\dfrac{1}{5}$ th
