Final answer:
The respiratory system becomes more efficient and the person starts using the same amount of oxygen more efficiently through continued aerobic exercise.
Step-by-step explanation:
The respiratory system responds to continued aerobic exercise over time by becoming more efficient. During exercise, the body requires more oxygen to produce energy, and the respiratory system adapts to meet this demand. As a result, the person will start to use the same amount of oxygen more efficiently. The lungs will become stronger, and the breathing rate and depth will increase, allowing more oxygen to be taken in and carbon dioxide to be expelled.
The efficiency of oxygen transport will also improve over time. This is due to adaptations in the cardiovascular system, such as an increase in the number of capillaries around the alveoli in the lungs, which enhances the exchange of oxygen and carbon dioxide. The amount of oxygen that can be transported by the blood and delivered to the working muscles will increase.
In summary, the respiratory system responds to continued aerobic exercise by increasing its efficiency. This leads to the person using the same amount of oxygen more efficiently, allowing for improved endurance and performance.
