Of the following animals, which has a digestive system similar to humans?

Swine, or pigs, have a digestive system that is quite similar to that of humans. Both species are monogastric, meaning they have a single-chambered stomach. This allows them to digest a variety of feedstuffs in a manner closer to how humans process food. Their digestion involves the enzymatic breakdown of food in the stomach and small intestine, similar to the human digestive process.

In contrast, cattle, sheep, and goats are ruminants, which means they possess a complex digestive system with a multi-chambered stomach. This structure allows them to break down fibrous plant material through a process called rumination. The difference in digestion between ruminants and monogastric animals reflects the types of diets they consume; ruminants digest roughage effectively, while monogastrics are optimized for more varied diets that include grains and proteins. Understanding these differences is crucial for managing their feeding and health needs effectively.
