Chapter 2: Problem 10

The function of the lungs in acid-base balance is to perform which of the following? A. Control \(\mathrm{HCO}_3\) levels B. Retain or blow off \(\mathrm{CO}_2\) C. Regulate potassium levels D. Maintain sodium levels

Short Answer

Expert verified
Answer: The primary function of the lungs in acid-base balance is to retain or blow off carbon dioxide (CO₂).

Step by step solution

01

Correct Answer

The correct answer is B. Retain or blow off \(\mathrm{CO}_2\)
02

Explanation

The primary function of the lungs in acid-base balance is to retain or blow off carbon dioxide (CO₂). The lungs work closely with the kidneys to maintain the body's acid-base balance. While the kidneys regulate \(\mathrm{HCO}_3\) (bicarbonate) levels and remove acid from the body, the lungs help in maintaining proper levels of CO₂ by either retaining it or expelling it through respiration.
