5 True/False questions
Villi → The last segment of the small intestine, about 12 feet long, and ends at the Ileocecal valve: controls the flow from the small intestine into the large intestine.
Surface Epithelium → Is either stratified or simple columnar.
Mucosa → The outer lining of the digestive tract, composed of simple squamous epithelium, and loose connective tissue.
Lamina Propria → Deep to the epithelial layer, loose connective tissue, and contains small blood vessels, small lymphatic vessels and lymphoid tissue, and small sensory and motor nerves.
Pharynx → 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.
