When we do strenuous physical exercise, breathing becomes faster. This is because the body’s demand for ‘oxygen increases’.
Explanation:
- During exercise, the muscle stretch and contract at a faster rate which ‘increases their demand’ for oxygen.
- The heart starts to pump blood at a faster rate to carry oxygen to the ‘different parts of the body’ for their energy requirement.
- This means, that more oxygen is taken up to meet the energy demand of the body during exercise.
