Transcript of Cow vs. Human Digestive system

There are a lot of similarities and differences between the cow and human digestive system.
The main differences between cows and humans in the digestive system are the teeth, mouth, stomach, gut and enzymes.
Cow digestive system
The digestion starts in the mouth with 32 teeth. After getting chewed in the mouth it goes to the Rumen. The Rumen is the main part of a cows four stomachs. The Rumen takes the food through the fermenting process for about four hours, then gets sent back to the mouth. The food gets grinded down so it can be sent to the other three parts of the stomach. The Reticulum, omasum, and abomasum are the other parts of the stomach that perform enzymatic digestion to the food. After it goes through the stomach the food is taken to the gut, where the nutrients is sucked out of the food, and finally out the back door.
Human digestive system
Digestion starts at the mouth where the tongue and teeth start to grind down the food. Then the food goes down the esophagus which is a tube connected to the stomach. Once it gets to the stomach the food is disintagrated by acids for about four hours. Then the food goes to the small intestine which is made up of the duodenum, jejunum, and ileum. They continue breaking down the food with enzymes from the pancreas. The jejunum's and ileum's main job is getting nutrients to the blood stream. After that it goes to the large intestine. The large intestine's job is to absorb water from the food as well as vitamins. Finally, it goes out the back door.
Cow vs. Human
Humans digestive system is longer than cows

Humans digestive system has enzymes to digest proteins but not cows

Human oral cavity has strong and sharp canines but cows have blunt canines

Humans have four canines but cows have two

Cows have a complex Rumen but humans have a simple stomach

Cows perform regurgitation during digestion but not humans
