Nephron Labeling Quiz

1. A label points to the coiled tubule that leaves the urinary pole of Bowman’s capsule. Which structure is it?

2. A blood vessel is shown entering the glomerulus at its vascular pole. Which label is correct?

3. Which sequence correctly follows tubular fluid after it enters the capsular space?

4. In a kidney cross-section, which structure belongs to a single nephron, extends into the medulla, and forms a hairpin-shaped path?

5. Which vessel should be labeled where blood exits the glomerular capillary tuft?

6. A leader line points to the tubule traveling from the cortex toward the medulla after the proximal convoluted tubule. Which label best fits?

7. Where does newly filtered fluid first collect after crossing the filtration barrier of the glomerular capillaries?

8. Several nephrons drain into a relatively straight tube that continues from the cortex through the medulla. Which label belongs on that tube?

9. A label points to renin-secreting modified smooth muscle cells in the wall of the afferent arteriole. What should it read?

10. A diagram of a juxtamedullary nephron shows long, straight capillaries running beside the loop of Henle in the medulla. What are they?

11. At the hairpin turn of a nephron loop, which segment carries tubular fluid away from the turn and back toward the cortex?

12. A convoluted cortical segment follows the thick ascending limb, passes close to its renal corpuscle, and then leads toward the collecting system. What is it?

13. Which label belongs on the double-walled cup that surrounds the glomerular capillary tuft?

14. A web of small vessels surrounds the proximal and distal tubules of a cortical nephron. Which label best identifies this network?

15. Within a renal corpuscle, what is the name of the capillary tuft where blood filtration begins?

16. Specialized epithelial cells in the distal tubule contact the vascular pole and monitor tubular sodium chloride delivery. Which label identifies them?
