Sorry not sure could be because of the amount of carbon dioxide blood increases?
Because your heart beats faster when you exercise.
The heart beats faster when we exercise because the heart pumps more blood and the body also needs more blood
Your heart beats faster because it is pumping blood around your body faster
No, the heart beats faster during exercise. The liver doesn't beat at all.
As you exercise, the muscles need more oxygen to work. The heart beats faster to get the oxygenated blood from the lungs to the muscles. The harder you exercise, the more oxygen the muscles need, the faster the heart beats.
Your heart beats faster and you breathe more because your blood cells need more energy to give to your muscles
Because the heart beats faster during exercise to ensure that oxygen gets to the working muscles.
your heart beats faster and ben rules!
It beats fast because your body needs to have blood 24/7 so it pumps so fast to keep your body warm, healthy, and alive
because it just beats faster
More blood is pumped around the body because the heart beats more. When the heart beats more the that makes the blood move around the body faster :)
The heart pumps, usually, at a steady rate between 60-80 beats per minute. The heart beats faster during exercise, fear or fright, and in illness. Ironically, regular exercise makes your resting heart rate become lower because the heart works more efficiently as a muscle. But having a fast heart rate, especially a persistently fast heart rate will not make you stronger; it actually makes your heart work HARDER.
