“Emphysema; Lungs and small airways too big” shows the principle of structures that are too big and therefore they cannot perform their function optimally.
The left sided image is a CT scan that shows normal lung architecture. The right image is a CT scan showing the ravages of the disease called emphysema caused by smoking. In emphysema the small airways and alveoli lose their elasticity and get stretched evolving into larger and larger structures. These small airways look like big black holes in the lung and the appearance is also referred to a “Swiss cheese”.
The art piece tells an educational story but also reflects the Goldilocks principle about size – just right and not too big!
