How often does the heart beat?
|
 | | Our hearts beat faster while running to create more nutrients and oxygen for our cells |
When we are sitting quietly, our heart might beat about 70 times a minute. But when we are moving about, our cells need more oxygen and nutrients, so the heart beats faster. If you run fast, your heart may beat more than 150 times a minute.
