<P> Fenestrated capillaries ( derived from fenestra , Latin for `` window '' ) have pores in the endothelial cells ( 60 -- 80 nm in diameter ) that are spanned by a diaphragm of radially oriented fibrils and allow small molecules and limited amounts of protein to diffuse . In the renal glomerulus there are cells with no diaphragms , called podocyte foot processes or pedicels , which have slit pores with a function analogous to the diaphragm of the capillaries . Both of these types of blood vessels have continuous basal laminae and are primarily located in the endocrine glands , intestines , pancreas , and the glomeruli of the kidney . </P>
where are fenestrated capillaries most likely to be found
endocrine glands intestines pancreas glomeruli of the kidney
