Describe the structural features of the renal corpuscle that enhance its blood filtering capacity
What will be an ideal response
Endothelial cells of the glomerular capillaries are fenestrated. Their basement membranes are part of the filtering mechanism. Podocytes with filtration slits between pedicels wrap the glomerular capillaries. The large surface area also contributes to filtering ability, as does the high glomerular hydrostatic pressure created by the arrangement of the afferent and efferent arterioles, in which the diameter of the efferent arteriole is smaller than that of the afferent arteriole.
