Difference Between Egestion And Excretion

Every living organism needs oxygen and nutrients for survival. In the process, they discharge products that can no longer be used by their system. These “wastes” can be categorized into two types based on their discharged material. The materials discharged during the process of Egestion are undigested matter leftover from the process of digestion. Excretion, on the other hand, discharges metabolic waste products. This is the main Difference Between Egestion And Excretion.

Difference Between Egestion And Excretion

Another difference between Egestion and Excretion are the types or organisms that use the two. For instance, Egestion cannot happen in plants as they do not have a digestive system. But they can excrete metabolic wastes like oxygen after the process of photosynthesis. Animals can undergo Egestion and Excretion as well. The other difference between egestion and excretion are summarized below:

Difference Between Egestion And Excretion

Egestion

Excretion

The process involves removing undigested waste products food from the body of the organism

The process involves removing wastes from the cells of organisms

Discharged materials are Undigested food and other toxic substances leftover from digestion

Discharged materials are Metabolic wastes such as carbon dioxide or oxygen

Egestion mainly happens through the anus or the mouth. (animals such as jellyfish use their mouth to both consume and discharge wastes)

Excretion happens through the nose, skin and the urethra

Only animals undergo esgestion

Excretion happens in both plants and animals

Conclusion

The difference between Excretion and Egestion lies in the type of wastes discharged from an organism. Egestion happens to be the undigested food materials leftover after the process of digestion in only animals. Excretion, on the other hand, involves discharge of metabolic waste from plants and animals.
