Transcript of Digestive System of a Wolf

Mouth
-In the mouth, the teeth are a fundamental part since it is a carnivore and its uses its teeth to slice and dice the food in the mouth. This is their alternative to chewing. A lubrication of its food is done with saliva. The tongue also helps when trying to push the food down the oesophagus.
Oesophagus
- The food enters the oesophagus and is placed in the stomach.
Stomach
- In the stomach, acids and other chemicals from the pancreas and liver are added to the mixture which is now considered as pulp. Since the diet of a wolf is just basically meat and water the stomach structure in not that complex compared to an herbivore's stomach structure.
Parts of the Digestive System of a Wolf

Liver
- Before the food enters further down the small intestine, it need to be neutralises the acid in the stomach by a substance called bile which is made in the liver and stored in the gall bladder. It also breaks down fatty molecules.
Small Intestines
- It enters the small intestine and breaks down proteins and fats.
Large Intestine
- After that it enters the large intestine. The food slows down since the body is getting the last chunks of nutrients from the food.
Colon
- After the food enters the colon. The colon reabsorbs the fluids and processes the waste product and it prepares for its elimination.

Comparisons to the Human and Wolf Systems
Differences:
- The Wolf's liver is twice the size of a human's liver
- The teeth have a different function to the human's teeth. It slices and dices the food instead of chewing which means that their teeth are sharper since they are carnivores.
- The digestive tract of a wolf is longer than to the human's. A wolf's digestive tract is 7m and a human's digestive tract is 5m.
- Coccidiosis is a disease that occurs in the intestines and it is caused from the protozoan parasite coccidia. This infests then damages the walls of the small intestine and sometimes the large intestine. Eventually the wolf dies. This disease doesn't affect the human as badly as how it affect the wolf.
