excrete (v.)

"to throw out or eliminate," specifically "to eliminate from an body by a process of secretion and discharge," 1610s, from Latin excretus, past participle of excernere "to sift out, discharge," from ex "out" (see ex-) + cernere "sift, separate" (from PIE root *krei- "to sieve," thus "discriminate, distinguish").
