Difference Between Secretion And Excretion

The body processes are expected with an opinion for the management and safeguarding of homeostasis throughout the body. The “secretion” and  “excretion” whose character is identical, since all are involved during the duration of the movement or passage of labor. Both procedures (secretion and excretion) take in and change unwanted parts of the entire body in a way. In bodily processes, we can find words that are quite similar in definition. Secretion And Excretion are many times used interchangeably. The major difference between secretion and excretion is that secretion is the movement of materials from one part to another part of the body. While excretion is a process of removal of waste material from living organisms. Given below in a tabular column is the difference between excretion and secretion.

Difference Between Secretion And Excretion in Tabular Form



The process of movement of materials internally – such as hormonal secretion, mucosal secretion, lubrication protection, etc. The process of removal of waste material from the body
Hormones, enzymes, and saliva are the materials that are secreted. Carbon dioxide, sweat, tears, faeces, and urine are the materials that are excreted from the body.
Active process Passive process.
Secreted substances are involved in the metabolism Excreted substances are no longer of use to the body
Example: Endocrine glands, digestive glands, salivary glands, liver, pancreas, and gallbladder are involved in the secretion process. Example: Lungs, skin, tear ducts, and rectum are involved in the process of excretion are involved in excretion process.
It is not toxic to the body and generally carries out several functions for the benefit of the body. It is toxic to the body.


Secretion is the process of expulsion (within the body) of some materials by a cell or gland that is used functionally elsewhere. It can be tissue that moves from 1 level to some unique. The secretion could be our procedure for releasing and transporting a particular compound substance from one place to a single place. The materials or substances are typically found in the hormone or cells of creatures.

Secretion Organs Examples:

The organs that are involved in secretion are Salivary glands, digestive glands, endocrine glands, pancreas, liver, and gallbladder.


Excretion is the process of expulsion of substances that are toxic or that are no longer useful by the body. It could be our removal of material in the resident dilemma. The eradication of metabolic waste from the creature’s body includes excretion. It balances adequate levels of dissolved water and substances in compound fluids and cells.

Key Difference b/w Secretion And Excretion

  • Excretion is commonly bodily waste, whereas secretion is also a vital supply that our bodies could summon and use.
  • The secretion is lively where, like the excretion, it is lively in character.
  • For excretion, the lungs and glands function as the first excretory organs. While the liver glands and also the adrenal tissues are used for functions to secretion.
  • Secretion includes these movements of material from one place the body to a certain place since all regions are important. While the excretion plan consists of discharge with materials in the resident dilemma.
  • Excretion is too important in stabilizing salt and water levels throughout the body.
  • The adrenal glands, liver, liver, endocrine glands such as thyroid, thyroid, adrenal glands, ovary, and testes play more essential functions during the duration of secretion
  • The lungs excrete carbon dioxide and water vapor, while the kidneys excrete urine as an excretory product.


  • The secretion and excretion are involved in the movement materials in the body.
  • Organs in the body are involved in secretion and excretion in humans and other living things.
  • They are important for the maintenance of homeostasis in the body.
