Question 19 (0.75 points) Saved A patient is found to have high levels of glucose in their urine. Which part of the nephron is likely not functioning correctly? Bowman's capsule Proximal tubule Loop of Henle Distal tubule Collecting duct

The part of the nephron likely not functioning correctly is the **proximal tubule**.<br /><br />Here's why: Glucose is typically filtered out of the blood in the glomerulus and enters Bowman's capsule. The proximal tubule is responsible for reabsorbing nearly all of this filtered glucose back into the bloodstream. If glucose is showing up in the urine (glycosuria), it means the reabsorption process in the proximal tubule is failing. The other parts of the nephron play roles in regulating water and electrolyte balance, but not primary glucose reabsorption.<br />
