IB SEHS Topic 2 - Exercise Physiology

Front

What is vital capacity?

Back

Total lung capacity minus residual volume.

Front

What are the principal structures of the ventilatory systems?

Back

Nose, trachea, bronchioles, alveoli

Front

What is the tidal volume?

Back

volume of air breathed in and out in a normal breath

Front

What is residual volume?

Back

volume of air still contained in the lungs after a maximal exhalation

Front

Which is a principal structure of the ventilatory system? Options: pulmonary artery, trachea, pulmonary valve, capillary

Back

trachea

Front

What is inspiratory reserve volume?

Back

additional inspired air over and above the tidal volume

Front

What is pulmonary ventilation?

Back

Inflow and outflow of air between the atmosphere and the lungs.

Front

Which structure is responsible for moistening the air entering the ventilatory system?

Back

Nose

Front

What is the action of the diaphragm (D) and the external intercostal muscles (EIM) during exhalation?

Back

D & EIM - relaxes

Front

Which feedback mechanisms are associated with the chemical control of ventilation during exercise?

Back

Increases in blood acidity levels
