NEET Zoology Urine Formation MCQ Question
Which of the following statements about urine formation is correct?
The collecting duct is primarily responsible for maintaining the osmolarity of urine through water reabsorption.
The loop of Henle is the main site for the reabsorption of glucose and amino acids.
ADH release is inhibited during dehydration, resulting in dilute urine formation.
The juxta-glomerular apparatus regulates GFR by releasing renin when there is an increase in blood flow.
Correct Answer
Detailed Explanation
The collecting duct plays a significant role in reabsorbing large amounts of water, thereby concentrating urine. Statement B is incorrect as the proximal convoluted tubule is primarily responsible for glucose and amino acid reabsorption. Statement C is false because ADH is released during dehydration to concentrate urine. Statement D is misleading as renin is released in response to a decrease in blood flow to regulate GFR.
