Cardiorespiratory fitness refers to...... a.Bones b. Muscles c. Brain d. heart lung function

Answers

Answer:D. Heart and lung function

Explanation:the word “cardio” relates to the heart

Final answer:

Cardiorespiratory fitness refers to how efficiently the heart and lungs work together to deliver oxygenated blood to the muscles during exercise. It's essential for cardiovascular health, quality of life, and longevity.

Explanation:

Cardiorespiratory fitness refers to the ability of the heart and lungs (option d) to supply oxygen-rich blood to the working muscle tissues and the capacity of the muscles to use oxygen to produce energy for movement. This involves the circulatory and respiratory systems' abilities to transport oxygen throughout the body efficiently, maintaining overall health and stamina.

An individual with high cardiorespiratory fitness can sustain large-muscle, dynamic, moderate-to-high intensity exercise, such as walking, running, bicycling, and swimming, for prolonged periods. This capacity is critical for preventing cardiovascular diseases, improving quality of life, and promoting longevity.
