Digestive System – Notes
The Human Digestive System
The alimentary canal includes organs such as the mouth, pharynx, oesophagus, stomach, small intestine, large and anus.
The mouth, the anterior opening of the alimentary canal, leads intestine the buccal cavity or oral cavity, which contains the teeth and the tongue.
The tongue helps push the food from the oral cavity into the pharynx, as passageway for air and food.
The pharynx opens into the windpipe or trachea and the oesophagus.
The stomach, an important organ of the alimentary canal, is located in the upper left part of the abdominal cavity between the oesophagus and the first part of the small intestine called the duodenum.
The duodenum, jejunum and ileum make up the small intestine.
