However, there is a clear cut difference between them. Excretion refers to the removal of metabolic waste substances from the body. That means that when the body is getting rid of substances it doesn’t need any longer like sweat,urine, carbon dioxide etc we use the term excretion. Some organs noted for excretory processes include the skin, lungs,tear duct, rectum etc. Secretion on the other hand refers to the release of mostly useful substances within the body. This is usually release from glandular organs which ejects these chemical substances like hormones, enzymes, saliva, digestive juices etc in response to a particular process or the presence of a particular thing. For instance, in the presence of food, the salivary glands secrete saliva whereas the digestive glands secrete digestive juices. In short, we excrete end product of metabolism whiles we secrete substances that will aid metabolism. 0 Login to Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerCancel replyYou must login to can add an answer.
