The proventriculus, gizzard, pancreas, duodenum (from ventriculus to pancreo-biliary ducts), jejunum (from pancreo-biliary ducts to yolk stalk) and ileum (from yolk stalk to ileocecal junction) were removed and weighed (without content and gall bladder).
The proventriculus and ventriculus contained a small amount of mucus.
Samples from brain, proventriculus, and ventriculus were embedded in paraffin wax, sectioned at 4 pm, and stained with hematoxylin and eosin.
Histology and histochemistry of the ventriculus Dolichoderus (=Monacis) bispinosus (Olivier, 1792) (Hymenoptera: Formicidae).
The parts of the digestive tract from anterior to posterior are the buccal cavity, pharynx, esophagus, crop, proventriculus, midgut (with associated gastric caeca), ventriculus, ilieum, colon, rectum, and anus.
The esophagus, proventriculus, and ventriculus (gizzard) were tied off from adjacent sections of the digestive tract to prevent mixing of contents.
Bacteria were present in large numbers in that structure alone, and not in the ventriculus (or digestive structure) as expected.
Commonly large, stout worms; usually three lips present, less often two or none; esophagus simple, muscular, lacking specializations, occasionally with posterior ventriculus, with or without appendix; intestine occasionally with one or more appendices at esophagointestinal junction; preanal sucker present in a few species; eggs usually with sculptured uterine layer, unembryonated when laid, juveniles infective to host in second (perhaps third) stage; parasites of all classes of vertebrates.
There was marked soft tissue enlargement of the caudal coelomic cavity with left lateral displacement of the ventriculus and intestines.
Two birds from each replicate were randomly selected on day 21, weighed, and slaughtered by cervical dislocation, to measure the weight of visceral organs (small intestine, pancreas, liver, proventriculus, ventriculus or gizzard, spleen, bursa of Fabricius).
Whole-body radiographs taken with the bird under anesthesia (anesthetic protocol as described previously) revealed a severely dilated, gas-filled proventriculus, ventriculus, and intestines orad to a tubular soft-tissue opacity in the ileo-ceco-rectal area (Figs 1 and 2).
The small intestine was divided into three segments: duodenum (from ventriculus to pancreo-biliary ducts), jejunum (from entry of the bile ducts to Meckel's diverticulum), and ileum (from Meckel's diverticulum to ileo-caecal junction).
