What is the Difference Between Rat and Human Digestive System?

🆚 Go to Comparative Table 🆚

The major difference between the human and rat digestive systems is that humans have a gallbladder, while rats do not. The gallbladder is responsible for storing and releasing bile juice, which plays a crucial role in the digestion of fats. Another significant difference is that rats have an enlarged large intestine, while humans do not. Rats also have a fermentation chamber to digest cellulose, which is not present in the human digestive system.

Apart from these differences, there are some similarities between the two digestive systems. Both humans and rats are mammals, and their digestive systems share many common features, such as mechanical and chemical digestion, as well as nutrient absorption.

    Feature Rat Digestive System Human Digestive System
    Gallbladder Rats do not have a gallbladder Humans have a gallbladder
    Fermentation Chamber Rats have a fermentation chamber to digest cellulose Humans do not have a fermentation chamber
    Size Rat digestive system is smaller than human digestive system Human digestive system is larger than rat digestive system
    Stomach Rat's stomach has two parts: Forestomach and Glandular stomach Human stomach is a single chamber
    Disaccharidases Activity Rat and human small intestinal disaccharidases activity is similar, except for sucrase Rat and human small intestinal disaccharidases activity is similar, except for sucrase
