Difference Between Secretion and Excretion – Class 11 | Chapter – 19 | Biology Short Notes Series PDF
Difference Between Secretion and Excretion: Excretion releases waste materials that cannot be reused, whereas secretion releases undesirable materials that can be reused.
- The process of excretion is passive, whereas secretion is active.
- Carbon dioxide, perspiration, tears, faeces, and urine are excreted by the body, whereas hormones, enzymes, and saliva are secreted by the body.
- The lungs, skin, tear ducts, and rectum is engaged in excretion, whereas the Endocrine glands, digestive glands, salivary glands, liver, pancreas, and gallbladder are involved in secretion.
- Tears, perspiration, and urine are materials released during the excretion process, whereas saliva and hormones are materials released during the secretion process.
Difference Between Secretion and Excretion
| Excretion | Secretion |
|---|---|
| It is the process of removing materials from a living organism. | It’s the transportation of material from one region to another. |
| In nature, excretion is a passive process. | In nature, secretion is active. |
| Tears, urine, carbon dioxide, and sweat are all excreted by humans. | Enzymes, saliva, and hormones are all examples of human secretions. |
| Body waste makes up the majority of excretion. | Secretion is a vital substance that our bodies can metabolize. |
| Plants excrete through their roots into their surroundings, as well as through the leaves and bark of their leaves and bark. |
Latex, resin, gums, and other secretions are found in the plant body. |
