Three major organs of excretion are the skin, kidneys and lungs. In the egestion process, undigested food, which is left over after digestion is discharged in animals. The process of removal of the waste products, produced in the cells of animals and plants is called excretion. They degrade complex lipids, such as cholesterol and its derivatives. In addition to its digestive function, saliva, by moistening and lubricating the bolus, favors swallowing, protects the oral mucosa and dissolves the particles; In this way, taste buds are stimulated and produce a sensation of taste. • The liver produces bile, which is stored in the gallbladder and then poured into the intestine.

Indigestible wastes are ultimately expelled. Another difference between Egestion and Excretion are the types or organisms that use the two. The vacuole and a lysosome unite, forming a digestive vacuole, and the products of digestion are absorbed across the vacuolar membrane. Digestion in protozoan organisms such as amoebas and paramecia takes place when a food particle is encased in a food vacuole. But they can excrete metabolic wastes like oxygen after the process of photosynthesis. A) Nutrition stages: A Nutrient and gas collection from the external environment. – Esterases. Lung breathing some gastropod mollusks, amphibians, reptiles, birds and mammals. Animals can undergo Egestion and Excretion as well. Excretion occurs in both plant and animals, where metabolic wastes are discharged. Summary of Egestion and Excretion: The process of discharging of the undigested food from the animal’s body is called egestion. The exchange surfaces are digestive absorption, which allows the entry of nutrients; the respiratory, which performs the exchange of gases, and the excretory, which expels waste substances generated by the animal’s metabolic activity abroad.

In the case of unicellular organisms that form food vacuoles, the vacuoles eventually fuse with the cell membrane and then rupture, releasing indigestible wastes to the outside. They degrade starch and glycogen and release glucose. The role of lysosomes in intracellular digestion. Excretion, on the other hand, discharges metabolic waste products.
