GCSE PE mechanics of breathing and spirometer trace

What muscles are used in breathing in

• diaphragm and intercostals

• diaphragm and lungs

• Abdominals

What equipment is used to measure air being inspired and expired?

• breathalyzer

• spirometer

• inspirometer

• expirometer

What is the volume that remains in the lungs even after a forceful exhale

• expiratory reserve
• residual volume
• inspiratory reserve
• total lung capacity

What do we call the normal shallow breathing volume?

• minute ventilation

• inspiratory capacity

• tidal volume

• vital capacity

The amount of air you can force out after a normal breath out

• Expiratory Reserve
• Functional Residual Capacity
• Vital Capacity
• Inspiratory Capacity

The amount of air you can still inhale after a normal breath in

• Vital Capacity
• Inspiratory Reserve
• Functional Residual Capacity
• Inspiratory Capacity

During inhalation:

• The diaphragm contracts & moves upward becoming dome shaped

• The diaphragm contracts & flattens

• The diaphragm relaxes & moves upward becoming dome shaped

• The diaphragm relaxes & flattens

During exhalation:

• The diaphragm contracts & moves upward becoming dome shaped

• The diaphragm contracts & flattens

• The diaphragm relaxes & moves upward becoming dome shaped

• The diaphragm relaxes & flattens

When we inhale, the Intercostal Muscles contract causing the Ribs to move...

• Upwards and Outwards

• Inwards and Downwards

When the diaphragm relaxes it moves back up into what shape?

• Cube

• Pyramid

• Dome

• Star
