Make your question clearer.  But I think this is a perfect explanation; the ability of the heart, lungs, and blood vessels to process and transport oxygenrequired by muscle cells so that they can contract over a period of time; cardiorespiratory endurance is produced by exercise that require continuous, repetitive movements. Hope I helped! :) -Duolingo
