How does Erich Maria Remarque use imagery in All Quiet on the Western Front?

Examples of Imagery:

The soldier is on friendlier terms than other men with his stomach and intestines. Three-quarters of his vocabulary is derived from these regions, and they give an intimate flavor to expressions of his greatest joy as well as his deepest indignation.

In himself man is essentially a beast, only he butters it over like a slice of bread with a little decorum.

My hands grow cold and my flesh creeps; and yet the night is warm. Only the mist is cold, this mysterious mist that trails over the dead and sucks from them their last, creeping life.
