After researching on the different digestive systems in differnent types of animals, I can finally conclude something.
I can conclude that these animals have different digestive system due to their lifestyle, habits, diet and many other factors.
For example, a cow needs to have four chambers of stomach. It helps the cow to bring the boluses of food up back into the mouth where they rechew their food. Also to keep the feed mixing by strong contractions, and to provide a suitable environment for the bacteria and protozoa to live.
Another example of having a digestive system due to a diet will be the snake. The salivary glands found in snakes include the palatine, lingual, sublingual and labial gland. These glands help moisten the prey for swallowing.
An example of a digestive system adapting to its habitat would be that of a shark. The liver is the largest organ and serves as a hydrostatic organ, helping the shark in buoyancy. The vast amount of oil created and stored in the shark’s liver, decreasing the weight of the shark and increasing its flotation.
Although there are many types of animals out there in the entire world, it is quite impossible for me to study everyone one by one. But still this is a good experience for me to know that different animals have so much difference in their digestive systems.
