Difference Between Egestion And Excretion

Living organisms need oxygen and nutrients for survival. The wastes product can be categorized into two types based on their discharged material. The major difference between egestion and excretion is that egestion is a process of discharging the undigested food from the body. It generally takes place through the anus and sometimes through the mouth. On the other hand, excretion is a process of removal of wastes products produced in the cells of plants and animals. It takes place through the urethra, skin, or mouth. In this article, you will learn about egestion vs. excretion in detail.

Difference Between Egestion And Excretion in Tabular Form

Egestion

Excretion

Egestion is a process of discharging the undigested food from the body Excretion is a process of removal of wastes products produced in the cells of plants and animals.
Remove undigested waste products food from the body of the organism Remove wastes from the cells of organisms.
Undigested food and other toxic substances leftover from digestion Metabolic wastes such as carbon dioxide or oxygen.
Associated with alimentary canal. Associated with kidneys.
Happens only in animals. Happens in both plants and animals
It is a major part of digestion. It is a totally separate life process.
The matter that is egested is faeces. The product that is excreted is urine, sweat, or carbon dioxide.

Egestion Vs. Excretion – Overview

A living organism eliminates the waste product produced in the metabolic process which supports life. Animals and plants have to eliminate these byproducts to avoid the toxicity of the system and carry on surviving in an ecosystem. There are two types of elimination of byproducts in the organism’s body i.e. Egestion and excretion. In excretion, an organism excretes the byproduct of a metabolic process using the different cellular and organ functions. Metabolic wastes are carbon dioxide or oxygen eliminates from the bodies of animals. While, in egestion, the elimination of undigested food from the digestive system of an animal occurs. Egestion is a process of eliminating byproducts of a metabolic process but it involves a digestive system and always happens in animals. It is associated with the alimentary canal. It is a major part of digestion.

What is Egestion?

Egestion is a process of discharging the undigested food from the body. It generally takes place through the anus and sometimes through the mouth. It takes place only in animals. Faeces are eliminated out of your body through anus. the food which has been left over after the process of digestion. Not only anus but it can also take place by the mouth but only sometimes. It is a part of digestion. The products discharged are undigested food and other poisonous substances left from digestion. Groups of animals egest unutilized food in a different way. the undigested food is transported to the cell membrane and released outside of the body in unicellular organisms. Many multicellular organisms do have not a specialized system. In hydra, for example, food is digested in the stomach sac, and the undigested food is egested through the mouth. Egestion does not occur in plants as they do not have a digestive system.

What is Excretion?

Excretion is the process where the waste is removed from the cells of the body. The products discharged are metabolic wastes such as carbon dioxide or oxygen. By excretion, the organism maintains acid-base balance and control the osmotic pressure. substances gone through different metabolic processes inside the cells through excretion. Excretory processes in animals are the exhaling step of respiration, sweating, and urination. It is generally associated with kidneys. It happens in both plants and animals. It is an important process in living organisms. Metabolic wastes are eliminated that the cells produce which needs to be removed in order for the cells to stay clean. Excretion may occur through sweat, urine, via the nose (carbon dioxide), kidneys and lungs.
