Question

The size of filtration slits of glomerulus is

• A. 10 nm
• B. 15 nm
• C. 20 nm
• D. 25 nm

Answer 1

The correct option is D 25 nm

The size of the filtration slits restricts the passage of large molecules like serum albumin and cells like red blood cells and platelets. Foot processes of podocytes interconnect with one another forming filtration slits (or slit pores). The size of filtration slits is about 25 nm.
