Etymology: "Excretors" is simply the plural of "excretor," so it carries the same history as its singular. The singular is built from the Latin verb "excernere," meaning "to sift out" or "to separate off," formed from "ex-" ("out") and "cernere" ("to sift, separate"). The English noun names an agent that performs excretion, the physical act of expelling waste from the body. Because the word is a plural, its meaning simply extends to several organisms or structures at once, such as the kidneys, skin, and lungs in a body that eliminates metabolic waste.
