Define vital capacity. What is its significance?
The respiratory system consists of a nose, trachea, alveoli, bronchioles, and lungs. The volume of oxygen that enters the lungs depends on the lungs' capacity, and this capacity changes with age, gender, and presence of respiratory disorders. There are four types of lung capacity: Inspiratory capacity, vital capacity, functional residual capacity, and total lung capacity. The vital capacity is defined as the maximum volume of air (oxygen) that a person exhales from the lungs after the maximum inhalation. The sum of inspiratory reserve volume, the tidal volume, and the expiratory reserve volume is equal to the vital capacity (VC). The amount of air that is expelled is nearly equal to the Forced Vital Capacity (FVC). The vital capacity is significant
