pe classwork: eoc review part 2
a healthy and efficient heart beats ____________ times per minute than a less efficient or unhealthy heart
more
fewer
the same number of times

Explanation:

A healthy and efficient heart can pump more blood with each beat, so it doesn't need to beat as many times per minute to meet the body's oxygen and nutrient needs. In contrast, a less efficient or unhealthy heart has to work harder and beat more frequently to supply the same amount of blood. So a healthy and efficient heart beats fewer times per minute.

Answer:

B. Fewer
