Which of the following statements is/are false?a. The collecting duct ...
Understanding the Statements
To determine which statements are false, let's analyze each one closely.
Statement A: The collecting duct extends from the cortex of the kidney to the inner parts of the medulla.
- This statement is true. The collecting duct indeed runs from the renal cortex, where it begins, down into the renal medulla, where it plays a crucial role in concentrating urine.
Statement B: Each human kidney has nearly one million complex tubular structures called Columns of Bertini.
- This statement is false. The term "Columns of Bertini" refers to renal columns, which are extensions of the renal cortex between the renal pyramids. However, the complex tubular structures in the kidney are actually nephrons, with each kidney containing about one million nephrons, not Columns of Bertini.
Statement C: The collecting duct can reabsorb large amounts of water to produce a concentrated urine.
- This statement is true. The collecting duct is responsible for the reabsorption of water, influenced by the hormone vasopressin (ADH), allowing the kidneys to produce concentrated urine.
Conclusion
- Thus, the only false statement is B, making the correct answer option 'B'.
In summary, while the collecting duct's function and location are accurate, the mischaracterization of Columns of Bertini as the primary tubular structures in the kidney leads to the identification of statement B as false.
