GO:0031911 cytoproct

Stable, specialized structure for extrusion of waste by the cell into the surrounding medium. PMID:10503189 PMID:23317460 PMID:27889663

The term cytoproct is specifically used to describe a structure in certain protozoa, particularly within the ciliates group. However, other unicellular eukaryotes, such as certain flagellates and amoebas, may have similar excretory structures, but they do not typically use the term cytoproct to describe them.
