The Four-Chambered Stomach

Grass Eater Strategy

Ruminants like cows and buffaloes swallow grass quickly and store it in the Rumen. They have specialized bacteria to digest complex cellulose.

Key Points

  1. Cud: Partially digested food that is sent back to the mouth.
  2. Rumination: The process of chewing the cud again.
  3. Rumen: First chamber where anaerobic bacteria live.
  4. Abomasum: The 'true stomach' where enzymes act on food.

Olympiad Fact

Humans cannot digest cellulose (plant fiber) because we lack the rumen and the specific bacteria that produce the 'cellulase' enzyme.
