Questions and Answers
Which of these methods would be most effective in allowing someone to precisely gauge the intensity level of his exercise?
During exercise, how does your body release heat?
By dilating blood vessels
How is blood flow related to lung function during exercise?
Blood vessels are dilated to increase the amount of oxygen carried in the blood, and the lungs work harder to meet the body's oxygen demands.

Study Notes
Exercise Monitoring and Physiology
- Taking pulse is an effective method to precisely gauge exercise intensity levels.
- The body releases heat during exercise by dilating blood vessels, promoting better circulation.
- Blood flow is critical for lung function during exercise; dilated blood vessels enhance oxygen delivery, while the lungs increase their activity to fulfill oxygen demands.
- Alexandra's ability to converse but not sing during dance class indicates a moderate heart rate during the activity.
- Oxygen levels carried in the blood to muscles increase significantly during exercise, supporting enhanced physical performance.
