DIGESTIVE SYSTEM
Digestion is the process of breaking down of complex foods to simpler compounds in the digestive
system
Digestive tract of mammals shows a basic fundamental plan with slight variation which corilate to the
kind of diet each animal eat.
Carnivorous have a slightly short digestive tract with reduced and functionless caecum and
appendix.This is because protein which is bulk of the food is digested in the gut.
Some herbivores with a single stomach example;rabbit has a large caecum and appendix,this increase
surface area for digestion of cellulose.
In the four chambered ruminant herbivores include cow
The four Chambers increase surface area for cellulose digestion
1.Rumen
2.Reticulum
3.Omasum
4.Abomasum
Alimentary canal
Also known as the gut
It is muscular and runs from the mouth to the anus
It is lined with glands and blood vessels
The process of digestion occur in the alimentary canal and then the digested food material is absorbed
to the blood stream.
Mouth
Food is introduced to the mouth through a process called ingestion
Food is mechanically broken down in a process known as mastication
Mastication reduces food to small particles and increase surface for enzymatic action.
The tongue is a long muscular organ on the floor of the mouth.
The tongue contains taste buds to taste.
