Question

select the correct answer.
what is cardiovascular endurance?
a. the ability of your heart and lungs to work during prolonged exercises
b. the ability of your heart to pump blood to your cells
c. the ability of your heart and lungs to fend off asthma
d. the ability of your heart to send de - oxygenated blood to the lungs

Explanation:

Cardiorespiratory endurance refers to the ability of the heart and lungs to supply oxygen - rich blood to the working muscles during prolonged physical activity. Option A correctly describes this as it mentions the heart and lungs working during prolonged exercise. Option B only focuses on the heart pumping blood (not including the lungs and the aspect of prolonged exercise). Option C is incorrect as fending off asthma is not the definition of cardiorespiratory endurance. Option D is about a specific function of the heart (sending de - oxygenated blood to the lungs) which is part of the normal circulatory process but not the definition of cardiorespiratory endurance.

Answer:

A. the ability of your heart and lungs to work during prolonged exercise
