Now, another thing that actually takes place on the skin is something called transepidermal water loss. And this is not the same thing as sweating. So actually, water can actually diffuse across the upper portion of our skin. So basically, water is lost as a result of this process of diffusion that takes place through the skin. And this is different than sweating. So, once again, the skin is an excretion organ as well as a secretion organ.
