sweat glands, they produce sweat , sweating is produce because we have hot , this process help us to expel waste subtstances we have 2 parts that are the skin and the sweet gland .Skin is the organ of touch but also is a part of the sweat glands.
And the urinary system is made up of kidney that is the moust important organ there funtions are
