Ruminant

The video tutorial explores various digestive systems, focusing on the ruminant system found in hoofed animals like cows. It explains the evolution of digestive tracts from simple gastrovascular cavities to complex alimentary canals. The ruminant system, with its four stomach compartments, allows animals to digest roughage efficiently. The video also covers unicellular digestion through phagocytosis and the pseudoruminant system in some vertebrates.

What is the difference between ruminant and pseudoruminant digestive systems?

What adaptations do different vertebrate digestive systems have based on their diets?

Explain the role of microorganisms in the rumen.
