Explanation:
Detailed explanation-1: -Tidal volume is essentially every breath a person takes. It is one of the main determinants of minute ventilation and alveolar ventilation. Minute ventilation, also known as total ventilation, is a measurement of the amount of air that enters the lungs per minute. It is the product of respiratory rate and tidal volume.
