  39. 39Which of the chambers does the regurgitated food used for "chewing the cud" come from? What would happen if it came from the abomasum?~Rumen
    ~The acid it had been mixed with in the abomasum would damage the oesophagus
  40. 40Which type of rumen is the gastric groove especially important for?Calves on a milk-based diet
  41. 41In which chamber are these type of papillae found?RumenIn which chamber are these type of papillae found?
  42. 42Why does the milk consumed by calves bypass the rumen?Doesn't need to be fermented: a lot of nutrients would be lost
  43. 43What is the structure of the ruminoreticular (gastric/milk) groove? What is its purpose?~Two spirally twisted grooves on wall of reticulum and lesser curvature of omentum
    ~Take milk directly into the omasum in calves so that it is not fermented by the rumen    What is the structure of the ruminoreticular (gastric/milk) groove? What is its purpose?
  44. 44What is the vagal reflex? How is it stimulated?~Lips of the ruminoreticular groove coming together to form a tube which allows milk to enter omasum directly from oesophagus
    ~Stimulated by suckling
  45. 45How is the vagal reflex useful in adult animals?Can use it to administer drugs directly into the omasum by stimulating it (eg. drugs which use copper sulphate which stimulates vagal reflex)
