integumentary system
"The integumentary system protects the human body from the outside world, from everything ranging from ultraviolet rays to scrapes on the knees. The integumentary system is like knights armor and is the primary system for the protection of the body. Sometimes a knight's armor gets a mark on it, much like the skin develops acne."
Both protect the inside
from outside agents that
might do damage to the inner
part of the body.
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.
