Y8u have a nthess tracker (like a FitBit) that tracks your heart rate. You have a routine cardio workout that you do and during it your heart rate averages 120 beats per minute. This is very consistent day-to-day. One day, you donate a unit of blood (about 10% of your total blood volume) and you rest that day, as recommended and drink plenty of water to let your blood volume recover. However, you are determined to keep up your workout schedule so the day after you donated, you do your normal workout. You find yourself struggling through the workout and see that your heart rate averages 140 beats-per-minute and you are out of breath. Concerned, you check your resting heart rate data and see that it is 65 bpm rather than your normal 50 bpm (you are in very good cardiovascular shape!). Explain why this is happening. Will it go back to normal? What will cause it to go back to normal?
