Transcript of Digestive System
Difference & Similarities
Hamster has long digestive tract compared to Tasmanian devil and a large cecum along the enzymes which helps to breakdown the plant material and cellulose. In contrast, Tasmanian devil has shorter digestive tract and small relatively caecum because they’re carnivores and their diet contains less plant chemical compounds. As the result, it is easier to chew. However, Tasmanian devil’s stomach secretes powerful digestive enzymes known as the ‘hydrochloric acid’ about 10 times much as the hamster.
A Tasmanian devil’s small intestine is three to six times length of its trunk and hamsters are 10 to 12 times the length of their body. But the major difference is Tasmanian devil has one stomach and hamster have two stomachs. This is because hamster is a rodent and herbivore. Therefore, nutrients from the foods are harder to fully breakdown at one since it is plant and cellulose and assimilate into their body due to the inefficiency of its digestive system.
The similarities between a hamster and a Tasmanian devil are the organs of digestive system, for instance, caecum, colon, liver, small intestine and anus. Since hamster is rodent mammal and Tasmanian devil is marsupial, their digestive tracts are different
Tasmanian Devil & Hamster
A Tasmanian devil has a simple digestive system, meaning that it does not regurgitate its food, it has only one stomach, and its intestines and stomach are not particularly enlarged. Food travels from the mouth, through the esophagus, and into the stomach, where acids break it down. Eventually the intestines receive the food, first the Small Intestine and then the Large Intestine. The small intestine pushes the food along by villi, and the bloodstream takes in nutrients. The large intestine has lack of villi, but they give some more nutrients to the blood stream and push the wastes out the anus.
Hamster has a two-part stomach consisting of a forestomach and a glandular stomach. Foods travel through hamster’s digestive system, starting with the oesophagus and ending in the colon, help break down the food and release the nutrients, but many nutrients still remain in the droppings after they’re eliminated from the body. They do eat their own feces, as part of their digestive regimen in order to bring more nutrients into their body that are excreted such as vitamins B and K which help to activate bone proteins. As the result, theses enhance calcium binding properties and prevent bone fractures. Hamster’s digestive system is very inefficient and does not remove entirely all the nutrients when first passing through the system.
