LINING EPITHELIUM OF THE STOMACH: a. simple columnar absorbtive b. stratified squamose nonkeratinized c. stratified squamose keratinized d. simple columnar secretory e. simple columnar ciliated

The correct answer is d. simple columnar secretory.<br /><br />The lining epithelium of the stomach is composed of simple columnar cells, which are single-layered, elongated cells. These cells are specialized for secretion, producing mucus, digestive enzymes, and hydrochloric acid. The presence of goblet cells within this epithelium further supports its secretory function, as goblet cells are responsible for secreting mucus. Therefore, the correct classification of the stomach's lining epithelium is simple columnar secretory.
