During exercise the breathing changes: Rate and depth increases.
Increasing the heart rate, rate of breathing and the depth of breathing enable the muscle cells to respire more than they do when the body is at rest. 
Also the blood flow and the rate of gaseous exchange in the lungs is increased. 

Answer:

The correct answer is – the rate and depth of breathing increase during exercise.

Explanation:

There is an increase in physical activity during exercise. Muscle cells need to respire more than they usually do during rest. The heart rate increases which leads to the rate and depth of breathing increases so than the more oxygen is absorbed into the blood, and carbon dioxide is eliminated from the blood.  

Further explanation:

  • The most important organs of the body of an individual come into action during exercise are the heart and the lungs.
  • The lungs helps in bringing oxygen into the body, for energy which produce carbon dioxide as waste product and removes it.
  • The heart has to pump more blood so the oxygen reaches to the muscles that are doing the exercise.  
  • During exercise muscles work harder than usual, thus the body uses more oxygen and produces more carbon dioxide as a waste product.
  • Breathing has to increase from about when the person is resting, during exercise so it can supply the extra demand of oxygen and removal of extra carbon dioxide released in the blood.
