Which of the following statements is TRUE regarding the regulation of acid-base balance in the body? A) The most powerful acid-base regulatory systems operate over a period of minutes. B) The pH of urine can vary significantly depending on the acid-base status of the extracellular fluid. C) Hypoxia and poor blood flow can lead to an accumulation of acids in the body. D) The kidneys play a minor role in correcting abnormalities of extracellular fluid H+ concentration.
Understand the Problem
The question is asking to identify the true statement related to the regulation of acid-base balance in the body from the given options. This involves understanding physiological concepts about acid-base regulation mechanisms.
Answer
The pH of urine can vary significantly depending on the acid-base status of the extracellular fluid.
The true statement is: The pH of urine can vary significantly depending on the acid-base status of the extracellular fluid.
Answer for screen readers
The true statement is: The pH of urine can vary significantly depending on the acid-base status of the extracellular fluid.
More Information
The pH of urine reflects changes in the body's acid-base balance, adjusting according to the hydrogen ion concentration and bicarbonate reabsorption in the kidneys.
Tips
One common mistake is to assume that kidneys play a minor role in acid-base balance regulation, when in fact, they are critical for this process.
