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 scattered among the absorptive cells in the epithelium of the small intestine and colon. These epithelial cells are specialized for secretion of mucus, which facilitates passage of material through the bowel.
