How many times is blood filtered in the kidney?

In summary, when considering a person with a mass of 60kg, the blood that circulates in their body is about 1/12 of their total mass. The kidneys filter 7.5 liters of blood per hour, and over the course of 24 hours, this amounts to 180 liters of blood and 99 liters of plasma. This means that the plasma is filtered 60 times in 24 hours, which is 2.5 times larger than the total volume of plasma.

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.

FAQ: How many times is blood filtered in the kidney?

How does the kidney filter blood?

The kidney filters blood through a specialized structure called a nephron. Nephrons have a glomerulus, which is a network of small blood vessels that filters waste and excess fluid from the blood.

What is the purpose of filtering blood in the kidney?

The primary purpose of filtering blood in the kidney is to remove waste products and excess fluid from the body. This process helps to regulate blood pressure, maintain proper electrolyte balance, and remove toxins from the body.

How long does it take for blood to be filtered in the kidney?

The process of filtering blood in the kidney takes about 30 minutes. This includes the time it takes for blood to travel through the glomerulus and for the waste and excess fluid to be removed.

Are both kidneys involved in filtering blood?

Yes, both kidneys are involved in filtering blood. Each kidney has millions of nephrons, which work together to filter blood and maintain the body's overall health and balance.
