egestion| Removal of undigested food or faeces from the gut. In most animals egestion takes place via the anus, although the invertebrate flatworms must use the mouth because their gut has no exit. Egestion refers solely to indigestible matter which is never absorbed into the cells – it should not be confused with excretion of the waste products of metabolism. |

No references found | Little information exists on the digestion and egestion rates for cephalopod and teleost prey in cetaceans; therefore, it is impossible to accurately estimate how long a period elapsed between the last feeding and the stranding event (Mintzer et al. The ratio of hexfuco: chl a increased in the pseudofeces in Experiment 1, suggestive of cell egestion, whereas in Experiment 2, the decrease in this diagnostic pigment ratio in the feces and pseudofeces suggests that these cells in the diet were consumed (Fig. 2) The mechanism was not by ejection due to internal tension and pressure, but is based on the passing out or egestion of accumulated dense matter (or fusion waste that could not efficiently generate more energy from further fusion) due to limited space for fusion and/or for accumulation of such dense matter. |
