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.
Caption: Goblet cell (yellow) in the mucosal lining of the small intestine (part of the digestive tract). A goblet cell secretes the mucus to protect the lining of the intestine and helps neutralize stomach acid.Inside the goblets cells are many mucigen granules (purple).When these are released into the intestine they will combine with water to form mucin, the main constituent of mucus. goblet cell secretes the mucus to protect the lining of the intestine and helps neutralize stomach acid.
