ACoils of afferent arterioles feeding glomeruli
BSheets of connective tissue between lobes
CClusters of renal corpuscles in the medulla
DBundles of collecting ducts opening at calyces
Answer & Solution
Correct answer: D. Bundles of collecting ducts opening at calyces
1. Urine formed by the nephrons drains into collecting ducts that run deep into the medulla.
2. Those ducts gather into bundles at the tip of each pyramid, and the bundle is the renal papilla.
3. The papilla delivers urine into the calyces for onward passage to the renal pelvis.
4. Renal corpuscles sit in the cortex, not in the medulla, so they cannot make up a papilla.
