How is digestion different in humans from that of ruminants?
Answers
Explanation:
The cow digestive system is not at all like the human digestive system. The main difference between the human digestive system and the cow's animal digestive system is simple: Cows have a stomach that consists of four compartments, commonly referred to as four stomachs. Cows spend the better part of the day eating, swallowing and regurgitating their food, and chewing it again before final digestion. Because a cow's teeth mostly grind their food, cows use their tongues – which is why they are so long – to help them gather and grasp grass for pinching off between their incisors and dental pad at the front part of their mouths.

The main differences between cows and humans in the digestive system are the teeth, mouth, stomach, gut and enzymes. 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.
Digestive system in animals is an important system in the context of digestion of ingested food into simpler forms that could be easily absorbed by the body cells.
This provides all the essential compounds needed by the body for the existence and development of the living organism. Different digestive systems have evolved according to different species, their feeding patterns, and their habitats. Ruminant species survive only on plant matter. They are herbivorous animals.
Therefore, the digestive system of ruminants is evolved with the presence of a rumen which is a complex stomach with four different compartments. Humans are omnivorous who depend on plant and animal matter both thus, their digestive system composes of one stomach. This is the key difference between digestion of humans and ruminants.
