Answer :
Mild exercise leads to a moderate increase in ventilation rate, while vigorous exercise results in a higher and more pronounced increase in ventilation rate.
Mild and vigorous exercise have different effects on ventilation rate. During mild exercise, ventilation rate increases as the body demands more oxygen to fuel the muscles. This increase in ventilation rate allows for more oxygen to be taken in and more carbon dioxide to be expelled.
On the other hand, during vigorous exercise, ventilation rate increases even more significantly to meet the greater oxygen demand. The body needs to remove more carbon dioxide and supply more oxygen to the working muscles, so it increases both the depth and frequency of breaths.
In conclusion, mild exercise leads to a moderate increase in ventilation rate, while vigorous exercise results in a higher and more pronounced increase in ventilation rate.
