Hint: All living organisms require oxygen and minerals for living. In this period, they eliminate products that cannot be used further by their system. These “wastes” can be classified into two kinds based on their eliminated material.

Complete Answer:
- The products eliminated during the process of Egestion are undigested material remaining from the process of digestion.
- Excretion is the process of elimination of the waste products found in the blood by filtering it by the kidney and is a process that occurs in the excretory system.
 - The differentiation between the process of excretion and egestion relies on the kinds of wastes eliminated from an organism. In the egestion process, undigested food, that is remaining after digestion is discharged in animals. Excretion takes place in both plants and animals, where metabolic wastes are eliminated.
- Osmoregulation is the controlling of the osmotic pressure of the fluids in the body via maintenance of water and salt concentration.

Sl.NoEgestionExcretion
1.It occurs via anus and sometimes via mouth.It occurs via urethra, skin or mouth.
2.It is a portion of the digestion process.It is a totally different life process.
3.The material that is egested as faeces.The products that are eliminated by excretion are urine, sweat and carbon dioxide.


In humans, osmoregulation occurs mainly via the kidney which rapidly filters blood and produces urine to discharge all the toxic materials from the body and maintain a proper Osmotic pressure of blood by maintaining the water and salt concentrations.

Note: Egestion cannot occur in plants as they do not contain a digestive system. But they are able to remove metabolic wastes like oxygen after the photosynthesis process. Animals can go through egestion and Excretion as well.
