Detailed explanation-1: -Humans, swine, rabbits, chickens and horses all have a simple stomach, which is also known as a monogastric digestive system. Carnivores and omnivores have monogastric digestive systems.

Detailed explanation-2: -A monogastric digestive system has one simple stomach. The stomach secretes acid, result-ing in a low pH of 1.5 to 2.5. The low pH destroys most bacteria and begins to break down the feed materials. Animals with this type of digestive system are better adapted to eat rations high in concentrates.

Detailed explanation-3: -Monogastric Animals In a monogastric digestive system, the stomach has a simple structure consisting of a single compartment. A number of species have a monogastric digestive system, including swine, horses, dogs, rabbits, and fowl.

Detailed explanation-4: -Monogastric herbivores, such as rhinoceroses, horses, and rabbits, are not ruminants, as they have a simple single-chambered stomach.

Detailed explanation-5: -The monogastric stomach has a columnar epithelium. The folded mucosa of the stomach forms longitudinal rugae. The folds form invaginations called gastric pits which are continuous with gastric glands.
