Answer:

2) By increasing the availability of oxygen

Explanation:

  • The lungs both provide energy by bringing oxygen into the body and removing carbon dioxide, which is produced as a waste product when you make energy.
  • The heart delivers oxygen to the muscles that are working out. Your body needs more oxygen and creates more carbon dioxide when you exercise and your muscles work harder.
