"Each lung is like a sponge and is made up of millions of tiny airspaces."
"The lung is like a ministerial official; with it comes functional coordination.This metaphorically compares the lung to the premier of a state the the heart to a king."
Essentials of Chinese Medicine, Volume 2
"The human lung is like a tree. The trachea (trunk) for conduction of air, conduction continues with the bronchi (branches), and after 20 divisions or so come alveoli, for gas exchange (like leaves). "
"The general description of Lung is that it is a subtle flow of energy and out of the five elements (air, fire, water, earth and space) it is most closely connected with air. However it is not simply the air which we breathe or the wind in our bodies, it goes much deeper than that. Lung is like a horse and the mind is the rider, if there is something wrong with the horse the rider will not be able to ride properly. Its description is that it is rough, light, cool, thin, hard, movable."
"Schematically the lungs are like a pair of balloons being filled by suction from the surrounding cavity. When a balloon is inside a jar, removing the air from the jar will make the balloon expand."
"If lung cancer is like a fast-moving wildfire, prostate cancer is like a slow-moving sloth. About 30% of men over age 50, and about 70% of men over age 70, have at some cancerous cells in their prostate glands. Yet most of them die from something else, and never know about these cells. "
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
