To discharge waste matter from the body through the kidneys, bowels, or skin; to eliminate bodily waste.
From Latin excernere (to sift out, discharge), which breaks down as ex- (out) + cernere (to sift); originally meant 'to separate out' and came to mean discharge of waste.
Your body is constantly excreting—not just when you use the bathroom, but also through sweating, breathing out carbon dioxide, and even shedding dead skin cells, so you're always getting rid of waste.
