Q5. a) What do you understand by the term GFR? What are the factors affecting GFR?

ANS- GFR stands for glomerular (glow-MAIR-you-lure) filtration rate. A blood test checks your GFR, which tells how well your kidneys are filtering.

It's important to know your GFR if you are at risk for kidney disease. A urine test will also be used to check your kidneys.

GFR is reported as a number.

• A GFR of 60 or higher is in the normal range.
• A GFR below 60 may mean you have kidney disease.
• A GFR of 15 or lower may mean kidney failure.

You can't raise your GFR, but you can try to keep it from going lower. Learn more about what you can do to keep your kidneys healthy.

Glomerular filtration is occurs due to the pressure gradient in the glomerulus. Increased blood volumeand increased blood pressure will increase GFR.Constriction in the afferent arterioles going into the glomerulus and dilation of the efferent arterioles coming out of the glomerulus will decrease GFR.
