"The arteries are like the distributing pipes of the Croton Reservoir, carrying the water to every dwelling, while the veins are like the springs and rills that unite to form brooks and rivers, and carry it back to the great reservoir."
" Arteries are like laminated tubes, their walls composed of many tissue layers, such as muscle, connective tissue, etc. The inside of the artery is covered with a thin layer of cells called "intima" - it is like a skin for the inside of the artery. The outside is covered with a tough layer called "adventicia". The middle is made up of muscle, elastic, and other tissues. The yellow arrow represents flow of blood."
"Healthy arteries are like hollow pipes. When they're wide open, blood flows through them easily"
"Arteries are like straws that direct pressurized blood from your heart to the rest of your body "
"The arteries are like a tree, with a single large trunk that gives off smaller branches, that themselves divide in turn into smaller branches, on and on until the branches become too small to see with the naked eye."
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.
