B Correct answer
Explanation

Blood enters the glomerulus through the afferent arteriole and exits through the efferent arteriole. This unique arrangement (both vessels being arterioles) helps maintain the hydrostatic pressure needed for filtration. The efferent arteriole has smaller diameter than afferent, creating pressure gradient. Renal veins drain blood from the kidney after it passes through peritubular capillaries.
