Which pair of structures comprises the renal corpuscle?

• A. proximal tubule and loop of Henle
• B. glomerulus and glomerular capsule
• C. collecting duct and distal tubule
• D. renal pelvis and calyces

Answer: (B)

The renal corpuscle is the filtration unit of the nephron, composed of the glomerulus and the glomerular capsule (Bowman’s capsule). The glomerulus is a knot of fenestrated capillaries where blood plasma is filtered, and Bowman's capsule surrounds these capillaries to collect the filtrate in the capsular space. Downstream from this unit lie the proximal tubule, loop of Henle, distal tubule, and collecting duct, which handle reabsorption and secretion, while the renal pelvis and calyces belong to the collecting system outside the corpuscle. Therefore, the structures that comprise the renal corpuscle are the glomerulus and the glomerular capsule.
