16
Q

Tidal volume

A

The amount of air entering the lungs during normal inhalation

17
Q

Total lung capacity

A

The amount of air in the lungs after a maximum inspiration breath

18
Q

Vital capacity

A

The amount of air that can be exhaled after a deep breath

19
Q

Residual volume

A

The amount of gas left over in the lungs after maximum expiration

20
Q

Total lung capacity

A

Vital capacity plus residual volume

21
Q

Emphysema

A

Destruction of lung tissue. Greater than normal expansion of lungs and poor recoil- increased residual volume

22
Q

Lung compliance

A

The ease of expanding the lungs- depends on lung tissue elasticity and alveolar tension

23
Q

Diffusion

A

Exchange of oxygen and CO2 across the alveoli
