Answers
Answer:
“Excretion” is the removal of material from a living thing while “secretion” is the movement of material from one point to another. ... For an example of excretion, humans excrete such materials as tears, feces, urine, carbon dioxide, and sweat while secretion, on the other hand, includes enzymes, hormones, or saliva.
Excretion vs Secretion
In body processes, we may encounter words that are quite similar in definition. We may often use these interchangeably. Not until we know the definitions, will we be able to use these words correctly. In this article, we shall tackle two of the common words that are used interchangeably.
Two of these words that we commonly exchange in usage are “excretion” and “secretion.” Let us examine the differences.
“Secretion” and “excretion” are the same in nature since both are involved in the passage or movement of materials. These words and body processes are needed in order to control and maintain homeostasis in the body. Both processes move and eliminate unwanted components in the body.
To further elaborate on these two processes, let us define both. “Excretion” is the removal of material from a living thing while “secretion” is the movement of material from one point to another. So, to think of it, secretion is active while excretion is passive in nature. For an example of excretion, humans excrete such materials as tears, feces, urine, carbon dioxide, and sweat while secretion, on the other hand, includes enzymes, hormones, or saliva. So, as we can see, excretion is mostly body wastes while secretion is important materials that can be metabolized and used by our bodies.
