Answered by sawakkincsem

The correct answer is option B- Heart Rate

When you exercise your heart rate increases. During exercise, your body require more oxygen which is why blood carries more oxygen to cells and the circulation speeds up. This happens as a result of first heart rate.

During exercise, your body muscles perform faster than a normal rate hence they need more oxygen than normal.
