proventriculus (plural proventriculi)

  1. (zoology) The part of the avian stomach, between the crop and the gizzard, that secretes digestive enzymes. [from 19th c.]
    • 2020, Tim Ecott, The Land of Maybe, Short Books, published 2021, page 201:
      In fulmars, the proventriculus is very baggy, and has thick wrinkled walls lined with glands that excrete the waxy oil which courting birds pass to one another in small amounts, perhaps as a way of scent-marking their mate.
  2. (zoology) A similar part of the digestive system in insects and myriapods. [from 19th c.]
