the main difference between the gfr and the filtration fraction is that the filteration fraction is mainly use to determine the functional ability of kidnet the filtration fraction is inversly propotion to the plasma flow and diractly propotion to the gfr while the and it is the fraction of the reanal plasmaflow while the gfr is the total amount of the plasma filtered by the nefron of both kidneys gfr valuu is 125 ml per minute and 180 liter per day

What does it mean when your GFR is low?

A GFR (glomerular filtration rate - of the kidney) that is just under 60 indicated mild renal insufficiency. If it is under 40, then moderate renal disease is present. If it is under 20, more severe renal disease is the case. When GFR is too low, wastes cannot adequately be cleared and dialysis is needed.


Dilation of the afferent arteriole decrease GFR?

no, it would increase GFR constriction would decrease GFR


How can you decrease the glomerular filtration rate?

gfr is the net results of the balance between hydrostatic pressures &colloid osmotic pressures of intra vascular compartment & within the Bowman's capsule,where the net pressure gradient is towards filtration.i.e. "Net filtration pressure".Any method which will reduce this net filtration pressure will reduce GFR.That can be achieved by increasing the plasma globulin ad albumin level(increase colloid osmotic pressure),hypotension and addition of vasocostrictor at afferent and vasodialtors at efferent tubule(reducing capilary hydrostatic pressure) or obstructing the free flow of urine(increasing Bowman's casular hydrostatic pressure)


What is The rate of urinary excretion of any solute is equal to?

How long for entire blood supply to be filtered?

A person's kidneys receive about 20% of the heart's cardiac output (~1200mL/min). A person has about 6 - 8L of blood depending on gender, body size, etc. So on average it will take about 5 - 7 minutes for a person's entire blood volume to reach the kidneys. But once the blood reaches the kidneys, it is the glomeruli that filters the blood. The average glomerular filtration rate (GFR) is 125mL/min or 180L/ 24hr. So it takes about 45 min - 1 hour for 6 - 8L of blood to be filtered.

What is a normal GFR?

A normal GFR or Glomerular Filtration Rate, is similar in both men and women. For adults it is between 100-130 ml/min/1.73m2. For children a GFR at 110 ml/min/1.73m2 is normal. GFR's are used to assess kidney damage or kidney disease. Normal GFR (glomerular filtration rate of the kidney) should be above 60.

What does low gfr mean?

GFR means glomerular filtration rate. It is a way to measure the kidney's function. In adults the GFR should be somewhere between 100 and 130, while in children it should be about 110. Since the GFR is a measure of the kidney's function it is used to help classify kidney disease. GFR > 90 with no signs of kidney damage like proteinurea = normal GFR > 90 with signs of kidney damage = Category 1 GFR 60-90 = Category 2 (mild) GFR 30-60 = Category 3 (moderate) GFR 30-15 = Category 4 (severe) GFR < 15 = Category 5 (kidney failure)
