What are excretion and secretion examples of?

Difference between Excretion and Secretion:

The excretory materials are tears, sweat, urine, co2,etc. The secretory materials are hormones, saliva, enzymes, etc.
The plants excrete substances through roots, leaves and bark. The plants secrete substances like latex, gums, resins, etc.

A secretion is a substance made and released by a living thing, like when your skin sweats. For example, the secretions of some frogs are a type of poison. Some secretions stay within an animal, like the bile secreted by our livers. Saliva is another secretion.

What is difference between secretion and excrete?

Both these processes involve the movement of materials in the body. But the difference between excretion and secretion is that excretion is the removal of waste from the body, whereas secretion involves the movement of materials within the body.

What are the 4 steps of excretion?

Secretion is an active process and excretion is a passive process.

What is “excrete” and “secrete”?

To summarize, the word ‘excrete’ means to remove waste from the body. ‘Secrete’ means for a body part to release something into the body, such as waste, nutrition, or hormones. Both words tend to be technical and fairly formal, and they are most often used in biology.
