Which structure surrounds the glomerulus?

Which structure surrounds the glomerulus?

• A. Renal capsule
• B. Ureter
• C. Renal pelvis
• D. Bowman's capsule

Answer: (D)

Bowman's capsule is the cup-shaped structure that surrounds the glomerulus. It encloses the tuft of capillaries with a visceral layer that hugs the glomerular capillaries and a parietal layer that forms the outer wall, creating Bowman's space where filtrate collects before moving into the nephron tubules. This setup allows filtration of plasma from the capillaries into the capsule, initiating urine formation. The other structures serve different kidneys’ roles: the renal capsule protects the kidney as a whole, the renal pelvis collects urine within the kidney, and the ureter transports urine to the bladder.
