2.26 describe the structures of the human alimentary canal and describe the functions of the mouth, oesophagus, stomach, small intestine, large intestine and pancreas

Mouth: responsible for adding saliva (responsible for providing enzymes) and crushing the food to make it easier to digest and be taken down the esophagus.

Esophagus: carries the food from mouth to stomach using peristalsis

Stomach: breaks down food further into its monomers (amino acids, glycerol, glucose, fatty acids etc)

Small intestine: absorbsion of all nutrients into the blood stream

Large intestine: absorbsion of all the liquid


Rectum: all the solid left over stays here until removed via the anus
