"The chyme is like a soup, and it is ready to be absorbed through the cells on the surface of the villi. Molecules of nutrients from your school lunch pass by diffusion, osmosis or active transport into the blood vessels in the villi. Whatever is not absorbed is moved to the large intestine."
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.
