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 lay scattered amongst other types of cells in the epithelium, mostly in the respiratory and intestinal tract. In some cases, they are less in number as compared to other types of cells whereas in tissues of colon, they can be found more profusely.
