Tidal volume

Answer 1

Vol. of air that enters the lungs during normal inhalation at rest as opposed to exercise

Question 2

Residual volume

Answer 2

Vol. of air left in lungs after maximum exhalation

Question 3

Inspiratory reserve volume

Answer 3

Vol. of air inhaled above tidal volume during a deep breath

Question 4

Expiratory reserve volume

Answer 4

Vol. of air exhaled above tidal volume during a deep breath

Question 5

Vital capacity

Answer 5

Total vol. of air breathed out after maximum inhalation

Question 6

Total lung capacity

Answer 6

Vital lung capacity + residual volume

Question 7

Minute ventilation

Answer 7

Vol. of air in/exhaled per minute.

Breathing frequency x tidal volume :)
