Answer #1

Inulin is a polysaccharide and it is excreated only through kidney ( by glomerular filtration). It neither reabsorbed nor secreated by renal tubules. Since inulin is completely removed only by glomerular filtration, its clearance (inulin clearance) is considered as glod standard for measuring Glomerular filtration rate (GFR), one of the kidney function test.

So answer is Inulin clearance is approximately equals to GFR of the kidney.

GFR- Glomerular filtration rate- used to determine kidney's function.
