| The jellyfishes, coral animals, ctenophores, and comb jellies have a rudimentary canallike cavity in their two-layered bodies for the ingestion, digestion, and egestion of food and wastes. |
| Egestion is the act of excreting unusable or undigested material from a cell, as in the case of single-celled organisms, or from the digestive tract of multicellular animals. |
| Beginning 8 to 10 sec prior to egestion, the pellet is moved orad by esophageal antiperistalsis. |
| The alimentary canal is a pathway used almost exclusively for the elimination of solid wastes of an indigestible nature, and the act of elimination by this means is termed egestion. |
| The excess energy required for partial digestion and egestion of unused food as feces may contribute to reduced growth displayed at high food concentrations. |
| Four terms are commonly associated with waste-disposal processes and are often used interchangeably, though not always correctly: excretion, secretion, egestion, and elimination. |
