BACKGROUND: The importance of digestive accessory glands and spleen in human, domestic animals and birds has been studied for many years. OBJECTIVES: The aim of this study was to investigate the structural features of these organs in see-see. METHODS: Regarding the present study, 14 male and female see-see were randomly selected, from which, tissue samples of three males and three females were obtained. After preparation in the usual way, the samples were stained using hematoxylin and eosin methods. RESULTS: Liver involves two lobes, including right and left ones. Posterior border of the left lobe has a short cut which results in division of the left one into two sections. Gallbladder is extended in visceral level of the right lobe, from middle to posterior edge of it. Due to the lack of full penetration of capsule blades into the liver's parenchyma, lobulated tissues are unknown. Epithelium of the gallbladder is of simple cylindrical type; however, some areas there have very few goblet cells. See-see's spleen is red-brownish, pear-shaped, and is located in the posterior part of visceral level of the liver's left lobe. Spleen is embedded by muscle connective capsule. There are no splits of spleen capsule into parenchyma of the gland. Pancreas is an elongated organ in the situation between two arms of duodenum which is divided into three lobes including dorsal, ventral and splenic. Very delicate and short blades of the capsule are penetrated into the gland and it is divided to lobules. The endocrine part of pancreas consists of alpha and beta islets of Langerhans in large and small sizes. CONCLUSIONS: The results show that the structure and tissues of the liver, spleen and pancreas, despite the slight differences in morphological aspects, are similar to other birds.
