Answer:The various organs of the human digestive system
beginning from mouth are as follows :
Mouth " Oesophagus " Stomach " Small intestine
(consisting of duodenum, jejunum and ileum) " Large
intestine (consisting of caecum, colon and rectum).
There are three digestive glands associated with
the alimentary canal. These are salivary glands,
pancreas and liver.
Carbohydrate digestion begins in the buccal
cavity itself as human saliva contains an enzyme
ptyalin which digests starch into maltose.
Gastric juice in the stomach, contains protein
digesting enzyme pepsin which breaks down protein
into pep-tones.
The pancreatic juice in the duodenum contains
trypsin for converting proteins into pep-tones and
peptides. It also contains amylase for breaking starch
into maltose.
The partially digested protein and carbohydrates
with the help of succus entericus completes digestion.
Amino acids and glucose are finally produced.
