Lung Volumes - L3 BTEC

The volume of air inspired or expired per breath is referred to as the:

• Vital capacity

• Tidal volume

• Pulmonary ventilation

• Breathing rate

The total volume of gas/air inspired (breathed in) or expired (breathed out) per minute:

• Vital capacity

• Tidal volume

• Pulmonary ventilation

• Breathing rate

Breathing rate (f) x Tidal volume (TV) =

• Vital capacity

• Tidal volume

• Pulmonary ventilation

• Breathing rate

Which lung volume is approximately 0.5 litres at rest?

• Vital capacity

• Tidal volume

• Pulmonary ventilation

• Breathing rate

Which lung volume is approximately 3.0 litres at rest?

• Vital capacity

• Inspiratory Reserve Volume

• Pulmonary ventilation

• Breathing rate

Which lung volume is approximately 1.3 litres at rest?

• Vital capacity

• Inspiratory Reserve Volume

• Pulmonary ventilation

• Expiratory Reserve Volume

Which lung volume is approximately 1.2 litres at rest?

• Vital Capacity

• Inspiratory Reserve Volume

• Residual Volume

• Expiratory Reserve Volume

The total lung capacity is calculated by adding the:

• Vital capacity + residual volume

• Tidal volume + residual volume

• Pulmonary ventilation + breathing frequency

• Breathing rate + frequency

Tidal volume can increase up to ___ times higher than at rest to cope with exercise demands.

• 4-6

• 1-3

• 100-150

• 5-9

Exercise causes an increase in breathing rate and depth of breathing. This is due to a greater need for _________ in the body and removal of carbon dioxide.

• fluids

• air

• oxygen

• lactic acid
