During exercise, the heart rate ______ due to effects of the sympathetic nervous system.Multiple choice question.decreasesbecomes constantincreases

Understanding the Question

The question refers to the physiological response of heart rate during exercise, particularly focusing on the influence of the sympathetic nervous system.

Analyzing the Choices

1. Decreases: This would typically not be accurate during exercise, as the body requires more oxygen.
2. Becomes constant: It is unlikely as heart rate tends to fluctuate based on intensity.
3. Increases: Generally, during exercise, the sympathetic nervous system is activated, leading to an increase in heart rate to meet the increased demand for oxygen.

Conclusion

The correct response is that during exercise, the heart rate increases due to the effects of the sympathetic nervous system.
