Which structure includes Bowman's capsule and the glomerulus?

• A. Renal cortex
• B. Renal sinus
• C. Juxtaglomerular apparatus
• D. Renal corpuscle

Answer: (D)

The key idea is that Bowman's capsule and the glomerulus together form the renal corpuscle, which is the filtration unit of the nephron. The glomerulus is a tuft of capillaries that filters plasma, and Bowman's capsule surrounds these capillaries to collect the filtrate in Bowman's space, directing it into the proximal tubule. This structure sits in the renal cortex as the initial site of filtration. The other options refer to broader regions or different structures: the renal cortex is the tissue region housing renal corpuscles, the juxtaglomerular apparatus is a regulatory complex near the glomerulus, and the renal sinus is the cavity containing the renal pelvis and calyces. Therefore, the structure that includes Bowman's capsule and the glomerulus is the renal corpuscle.
