5 True/False questions
Mechanical processing → 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.
How the Small Intestine Increases Surface Area? → Plicae, Vili, and Microvilli.
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.
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.
Duodenum → The first segment of the small intestine, begins at the pyloric sphincter: which controls flow from the stomach to here, about 1 foot long, and it receives: chyme from the stomach and digestive enzymes and buffers from pancreas and liver.
