How many times is blood filtered in the kidney?

Click For Summary
SUMMARY

The kidneys filter approximately 7.5 liters of blood per hour, resulting in a total of 180 liters filtered in a 24-hour period. Given that the average person weighing 60 kg has about 5 liters of blood, the plasma volume is calculated to be 2.75 liters, which is 0.55 times the total blood volume. The plasma is filtered 60 times in 24 hours, leading to a filtration rate of 2.5 times per hour. This establishes a clear understanding of kidney filtration rates and their relation to blood volume.

PREREQUISITES
  • Basic understanding of human anatomy and physiology
  • Knowledge of blood volume calculations
  • Familiarity with renal function and filtration processes
  • Concept of plasma versus blood volume
NEXT STEPS
  • Research the renal filtration process in detail
  • Study the role of nephron structure in blood filtration
  • Explore the implications of kidney function on overall health
  • Learn about the effects of dehydration on kidney filtration rates
USEFUL FOR

Students studying human biology, healthcare professionals, and anyone interested in understanding kidney function and blood filtration processes.

The blood that circulates in our body is about 1/12 of our mass. If the kidneys filter 7.5 liter of blood a hour, then how many times does it filter in the kidney the whole blood of a person will mass 60kg?
Here's what my teacher did:
1/12*60=5 liter blood
0.55*5=2.75 liter plasma of blood.
The plasma is filtered 60 times is 24 hours. (how did she find that?)
24 hours ->60 times the plasma filters
1 hour -> x
x=2.5 times
Do you understand her explanation? What should I do next?

If the kidneys filter 7.5 liters of blood in one hour, how many liters do they filter in 24 hours? How many times larger is this than the volume of plasma?
 
In 24 hours 180 liters blood and 0.55*180=99 liters plasma.
 
What should I do next?
