100

The amount of air that moves in and out of the lungs in one quiet breath

Tidal volume

100

The pressure gradient between the atmosphere and the alveoli is known as the:

Transrespiratory Pressure

100

What is the opposite of Elastance?

Compliance

100

What reflex keeps the lungs from over-distending?

Hering-Breuer reflex

200

Short episodes of rapid, uniformly deep breathing, then apnea

Biot's

200

Maximum amount of air that the lungs can accommodate is known as the:

Total Lung Capacity

According to Poiseuille's Law, the most influential factor for flow or pressure is: 

Radius

200

If you compliance value is increasing are you getting better or worse?

Better

200

The basic rhythm of ventilation is controlled by:

Medulla oblongata
300

Crescendo-Decrescendo type breathing

Cheyne-Stoke's

300

The volume of air left in the lungs once the forces acting on the lungs balance out at exhalation is called:

Functional residual capacity

300

The pressure that it takes to get the alveolus to begin to open and expand is known as the:

Critical Opening Pressure
