Cardiorespiratory endurance is

The ability of the body to perform large muscle dynamic exvercise at moderate to high levels of intensity

2

Cardiorespiratory system

Picks up and transports oxygen, nutrients and other key substances to the organs and tissues that need them

6

Heart beats

At a rate of 50-90 beats a minute. It’s not good to have it high the muscle could wear out

7

Cardiac output

Combination of faster heart rate and greater stroke volume means the heart pumps and circulates more blood per minute. Five quarts of blood is circulated per minute at rest, but up to 20 quarts per minute during intense excercise

8

Blood flow

blood flow changes 15-20 percent of blood is distributed to the skeletal muscles, during intense exercise 85-90 % are delivered to working muscles
