In which part of the nephron does the majority of water reabsorption occur during urine formation?
Answer
Proximal convoluted tubule
The correct answer is Proximal convoluted tubule — Select the proximal convoluted tubule as the correct answer.
Step-by-step solution
- Recall the sections of the nephron: Bowman's capsule, proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting duct.
- Remember that about 65‑70% of filtered water is reabsorbed in the proximal convoluted tubule.
- Select the proximal convoluted tubule as the correct answer.
Common mistake: Confusing it with the loop of Henle, which reabsorbs additional water but not the majority.
