Eliana's doctor told her that she was suffering from celiac disease, and that her body was reacting to gluten in the food she was consuming. Another result of her blood tests was that she had elevated antibodies that were a consequence of an immune response to the gluten. If Eliana eliminated gluten from her diet, he explained that her symptoms would dissipate and the damage to her intestine wall should gradually return to normal. What is true of the mucosa of a healthy small intestine? a) Goblet cells produce mucus to protect the epithelium. b) Cilia move food through the canal. c) It has a simple columnar epithelium. d) It has a stratified squamous epithelium. e) Parietal cells produce digestive enzymes. f) The folds of plicae circulares, villi, and microvilli dramatically increase the surface area for absorption.

the correct option is "goblet cells mucus product to protect the epithelium".

Explanation:

When disorders such as celiac disease manifest, there is acute damage to the mucosa, where the amount of antibodies and inflammatory response increases in the walls of the intestinal lumen.

the rest of the statements that are written are false because the epithelium of the intestinal tract is columnar but not simple, but specialized since it presents cilia and microvilli that are due to increasing the absorption surface, NOT of food drag (this dragging function happens with the cilia of the respiratory tract that drag the antigens that are aspirated in the breath with their movements).

On the other hand, it has been shown that those cases of celiac disease where diets without TACC are respected, their acute inflammatory response - chronic disappears and goblet cells lubricate the lumen to protect it, moisturize it and maintain the function of the mucosa.

i believe that the answer to the question provided above is that the role of campaign committees is to act as a bridge between state and local campaigns.
