Copper is used as medicine. Copper is used for treating copper deficiency and the anemia it may cause. Having too little copper (copper deficiency) is rare. It sometimes occurs in people who get too much zinc from diet or supplements, have intestinal bypass surgery, or are fed by feeding tubes.
A goblet cell is a glandular, modified simple columnar epithelial cell whose function is to secrete gel-forming mucins, the major components of mucus.
Goblet cells are found scattered among other cells in the epithelium of many organs, especially in the intestinal and respiratory tracts. In some areas, their numbers are rather small relative to other cell types, while in tissues such as the colon, they are much more abundant.
