Explain the process of rumination in ruminant animals.

• Rumination is the process of animals migrating to different feeding grounds.

• Rumination is the process of animals running in circles in their enclosure.

• Rumination is the process of animals hibernating during the winter months.

• Rumination is the process of regurgitating food from the rumen, re-chewing it, and then swallowing it again.

What is the function of the omasum in the ruminant digestive system?

• Absorb water and nutrients

• Storing food temporarily

• Producing digestive enzymes

• Grinding food into smaller particles

Compare and contrast the monogastric and ruminant digestive systems.

• Monogastric digestive system has a single-chambered stomach, while ruminant digestive system has a four-chambered stomach.

• Monogastric digestive system has a two-chambered stomach, while ruminant digestive system has a single-chambered stomach.

• Monogastric digestive system has no stomach, while ruminant digestive system has a two-chambered stomach.

• Monogastric digestive system has a four-chambered stomach, while ruminant digestive system has a single-chambered stomach.

What is hindgut fermentation and which animals utilize this digestive process?

• Fish, reptiles, and amphibians

• Horses, rabbits, and some rodents

• Cows, pigs, and chickens

• Dogs, cats, and birds

Explain the function of the cecum in hindgut fermentation.

• Site for microbial fermentation of fibrous materials

• Location for the production of digestive enzymes

• Storage of excess water in the digestive system

• Site for absorption of nutrients from the digested food

What are some examples of ruminant animals?

• Lions, tigers, and bears

• Rabbits, guinea pigs, and hamsters

• Cows, sheep, and goats

• Pigs, horses, dogs, and cats
