Predict Question 1: With emphysema, there is a significant loss of elastic recoil in the lung tissue and a noticeable, exhausting muscular effort is required for each expiration. What lung values changed from those of the normal patient in the spirogram when the patient with emphysema was selected? For liquids, you just put it in a volumetric measuring device such as a graduated cylinder, For the volume of solids that cannot simply be measured with L x W x H which will give you an answer in units of m â€¦ easurement cubed. Which respiratory process is impaired the most by emphysema? Why did these values change as they did? Recall that airflow is achieved by the generation of a pressure difference between atmospheric pressure on the outside of the thoracic cavity and intrathoracic pressure on the inside. A quilt is made up of patches of cloth intricately stitched together to make the final product. Now consider the accuracy of your predictions what changed versus what you expected to change.
