How secretion and excretion both are different? explain in simple language.

Excretion is the removal of material from one living thing, for example. Humans excrete tears, sweat, carbon dioxide etc.

Secretion is the movement of material from one point to another, for example.  Humans secrete enzymes, hormones, saliva etc.

Basically in summary excretion is the removal of physical material and secretion is the movement of biological materials from one point to another.

I hope this was clear enough lol

well, i believe that the answer is 2. : 3
