Abstract
The avian pancreas is located in the abdominal cavity of all birds on the right side; it is tightly bound by mesentery and blood vessels in position between the descending and ascending duodenal loops. This organ varies greatly in size, although it is always well formed and exhibits discrete characteristics. It varies in weight, from 2 to 4 g in 1.5–2.1 kg adult chickens to a mere fraction of a gram in most passerine species, whose body weight may be at the most a few grams. Generally, it has a smooth macroscopic appearance, is yellowish white in color, and does not exhibit the highly vascular appearance so common to other vertebrate endocrine glands such as thyroid and adrenal tissue, etc.
