- a A common passageway for solid food, liquids, and air that is shared by the digestive and respiratory systems, and food passes through this to the esophagus.
- b Mucous cells, Parietal cells, and Chief cells.
- c A hollow muscular tube, transports solid food and liquids to the stomach, and passes through the diaphragm muscle to get from the larynx to the abdomen.
- d Folds in the intestinal lining, which increase surface area and are covered with villi.
- e Simple columnar epithelium which invaginates to form gastric glands.

5 True/False questions
How the Small Intestine Increases Surface Area? → Plicae, Vili, and Microvilli.
Muscularis → The inner lining of the digestive tract and consists of its own three layers: epithelium, lamina propria: loose CT, and muscularis mucosae: a thin smooth muscle layer.
Stomach, Small Intestine, and Large Intestine Surface Epithelium → Function is digestion and absorption, and are lined with simple columnar epithelium for rapid transport across the epithelial lining.
Functions of the Small Intestine → Duodenum, Jejunum, and Ileum.
General Organization of the Digestive Tract → The epithelial lining is continuous, at the mouth and at the anus, with the external environment, it must accommodate these transitions at either end while remaining moist, it must also be very thin to accomplish both digestion and absorption, and it must handle the rapid turnover of its epithelial cells due to mechanical and chemical insults while protecting the deeper tissues against: chemical stresses corrosive effects of digestive acids and enzymes), mechanical stresses, such as abrasion, and pathogenic bacteria.
