Explanation:
Detailed explanation-1: -Each breath contains around 500-600 ml of air, this is called the Tidal Volume (the depth of inhalation). People usually take around 10-15 breaths per minute when resting. This is described as the Respiratory Rate.
Detailed explanation-2: -The volume of air inspired or exhaled by a healthy man per minute is known as tidal volume which is 500 mL. The breathing rate for a normal person is 12-15 breaths per minutes. So, a normal person inhale or exhale around 6000 to 8000 mL air per minute.
