Question

The size of the filtration slits present in the glomerulus is

• A. 10 cm.
• B. 15 nm.
• C. 25 nm.
• D. 10 nm.

Answer 1

The correct option is C 25 nm.

The filtration slits present in the endothelium of the glomerulus are of the size 25 nm that can allow the plasma and solutes to diffuse in but not the blood cells. So the filtrate in the Bowman's Capsule that has diffused in from the glomerulus is colourless due to an absence of RBCs.

Hence, the correct answer is '25 nm'.
