There are different parts of alimentary canal namely
a) Mouth- Mouth contains saliva. It is rich in salivary amylase that hydrolysis polysaccharides to simple sugars.
b) Esophagus- It is a long narrow connecting tube between the mouth and stomach. Through, the peristaltic movements the food is pushed from mouth to the stomach.
c) Stomach- It contains proteases viz. trypsin that hydrolysis the proteins into simpler molecules. The pH of stomach is acidic which helps these proteases to work at their optimum pH.
d) Pancreas- It produces pancreatic juice which is released in the small intestine. The juice contains digestive enzymes viz. proteases, lipases and amylase that break proteins, lipids and sugars into small molecules.
e) Small intestine- It contains all types of hydrolases that produces small molecules. It also contains villi and microvilli that aids in the increased absorption of these small molecules.
f) Large intestine- It allows the absorption of water and storage of waste material as feces.
g) Anus- It the last part of the alimentary tract and the opening that allows the feces to be pushed out of the body by the means of peristaltic movement in the large intestine.
