Study Notes
Alimentary Canal and Gastrointestinal Tract
- The organs that make up the alimentary canal or gastrointestinal tract are the mouth, esophagus, stomach, small intestine, and large intestine.
Mucosa Function
- The mucosa, a layer of epithelial tissue, lines the gastrointestinal tract and has several functions, including absorption of nutrients, secretion of mucus, and protection against infection.
Accessory Digestive Organs
- The liver, gallbladder, and pancreas are considered accessory digestive organs because they produce secretions that aid in digestion, but are not part of the continuous tube of the gastrointestinal tract.
Muscular Tube
- The mouth, esophagus, stomach, small intestine, and large intestine form a long, continuous muscular tube that extends from the mouth to the anus.
Pancreas Function
- The pancreas is an accessory organ that produces digestive enzymes that break down carbohydrates, proteins, and fats, and secretes bicarbonate to neutralize stomach acid.
