Which structure is contained in Bowman's capsule?

Which structure is contained in Bowman's capsule?

• A. Cortex
• B. Renal capsule
• C. Glomerulus
• D. Renal hilum

Answer: (C)

The key idea is the relationship between Bowman's capsule and the glomerulus in the nephron. Bowman's capsule encloses the glomerulus, a tuft of capillaries where filtration happens. Blood pressure forces plasma through the filtration barrier formed by the glomerular endothelium, basement membrane, and podocyte slits, and the resulting filtrate collects in Bowman's space inside the capsule. The other kidney components mentioned—cortex, renal capsule, and renal hilum—are larger kidney structures or regions, not structures contained within Bowman's capsule.
