Prof.Marwa Abd Elaziz Physiology of Respiration Lecture 8 : Elastic properties of the lung
RRS-209
Elasticity is a measure of how easily the lungs can be stretched and is conventionally expressed as ______
Compliance
The lungs and the chest wall are ‘ locked together’ by the ______ space
intrapleural
The intrapleural space is airtight. So, the lungs are as firmly pressed to the chest wall as a suction cup attached to a ______
window
Lung compliance is the volume change that could be achieved in the lungs per unit ______ change
pressure
These distorting forces are usually those of intrapleural pressure, which becomes more negative to bring about inspiration and then becomes less negative, and the elasticity of the lungs leads to ______ expiration
quiet
Test your understanding of the elastic properties of the lung, surfactant function, and the work of breathing in respiratory physiology. Explore factors affecting lung compliance and compare types of work of breathing.
