Which of the following statements is not correct?a)taking in of oxygen...
Explanation:
Inhalation and Exhalation:
- Inhalation is the process of taking in oxygen-rich air into the lungs.
- Exhalation is the process of giving out carbon dioxide-rich air from the lungs.
Correct and Incorrect Statements:
- The correct statement is: "Taking in of oxygen is inhalation." This is true as inhalation involves breathing in oxygen.
- The correct statement is: "Giving out of carbon dioxide is exhalation." This is also true as exhalation involves breathing out carbon dioxide.
- The incorrect statement is: "Taking in of carbon dioxide is inhalation." This is incorrect because inhalation involves taking in oxygen, not carbon dioxide.
- The statement "Breathing rate is the number of inhalation and exhalation in one minute" is correct. Breathing rate is indeed measured by counting the number of complete inhalation and exhalation cycles in a minute.
Therefore, option B, which states that taking in carbon dioxide is inhalation, is not correct. Inhalation is the process of taking in oxygen, while exhalation is the process of giving out carbon dioxide.

Therefore, the correct answer is Statement B: taking in of carbon dioxide is inhalation.
