• what happens to any undigested grass

  it passes through to the reticulum chamber and it is formed into cud
• what happens once the undigested grass is converted into cud


  the cud is regurgitated into the mouth for further chewing
• what happens to increase the surface area of the grass for more cellulose digestion


  the cud will be regurgitated multiple times
• what happens to the cud that isn't regurgitated
