well-developed microvilli , occurrence of cored vesicles , dense granules , multivesicular bodies and phagosomes in the adluminal filamentous zone , and a strong accumulation of mitochondria in the basal part of the duct epithelium at the dermal segment , as well as an accumulation of small clear vesicles beneath the surface of the luminal cells of the epidermal segment are all prominent in the eccrine duct and concomitant with the special function of the human eccrine duct , i.e. , absorption of ions to make the sweat hyotonic and an active endocytosis of some material from the sweat .
