Sweat glands (Human Skin), 10X

I don't think this is a sweat gland. Please go to Plate 44 in your book- you can see what a sweat gland should look like. The duct segment and secretory segment should be lined with epithelium (cuboidal and columnar) - what you've labeled don't have this type of epithelium, and there's no lumen on the inside, as there should be. Please take a new photo - maybe try a new slide, and look for epithelial structures.
