PATHOLOGY

Detailed explanation-1: -The amount of air that moves in and out with each normal breath is called as tidal volume. Each relaxed breath takes in and out about 500 ml air, so, tidal volume is 500 ml.

Detailed explanation-2: -Tidal volume is the volume of each breath as measured during inspiration or expiration or averaged for the entire respiratory cycle.

Detailed explanation-3: -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.

Detailed explanation-4: -Tidal volume is the volume of air you breathe in a single breath. Exercise causes an increase in tidal volume because your requirements for oxygen go up. This increase is mediated in different ways depending on when it occurs during your exercise.
