5 Multiple choice questions
- Function is ingestion and to transport along the length of the tube, and lined with stratified epithelium for protection.
- 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.
- Removal of waste products (feces) from body.
- 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.
- Is either stratified or simple columnar.
5 True/False questions
Digestion → Occurs when materials enter digestive tract via the mouth.
Submucosa → Deep to the mucosa, dense irregular connective tissue, and contains large blood vessels, large lymphatic vessels, and large nerves.
How the Small Intestine Increases Surface Area? → Function is digestion and absorption, and are lined with simple columnar epithelium for rapid transport across the epithelial lining.
Submucosal Nerve Plexus → Contains sensory neurons that sense chemical changes in the lumen, and motor neurons (sympathetic and parasympathetic) that innervate the muscularis mucosae.
Ileum → Fingerlike projections, which increase surface area.
