MCAT Question of the Day


  • Q:

    Rabbits digest most of their food in their hindgut - their large intestine and cecum. Part of the digested material is passed as feces while part is passed as a nutritious cecotrope which is then consumed once more. Assuming the rabbit digestive system is otherwise like a human digestive system, which of the following is most likely the reason for the consumption of the cecotrope?

     

    A

    rabbits have poor vision and are unable to distinguish food from the cecotrope

    B

    the digested contents of the cecotrope must be mixed with food to aid digestion in the stomach

    C

    the cecotrope needs a second pass through the digestive system for the nutrients to be properly absorbed in the hindgut

    D

    most nutrient absorption happens in the small intestine so the digested cecotrope must be re-ingested so it will pass through the small intestine for nutrient absorption
