Gross anatomy of the respiratory system in goose (Anser anser domesticus)*: Bronchi and sacci pneumatici

Abstract

In the study, the macroanatomy of the bronchi and sacci pneumatici were examined in details in 7 domestic mature geese (Anser anser domesticus) with 4500-5000 g live weight. The left and right bronchus primarius seperated from trachea branched into four groups of bronchi secundarii that depart from the bronchus primarius called as bronchi mediodorsales (bmd), bronchi medioventrales (bmv), bronchi lateroventrales (blv), and bronchi laterodorsales (bld). The number of bmd, bmv, blv and bld were 4, 10, 10 and 25-30, respectively. It was seen that some of these bronchi were connected with pulmo and some of them were connected with sacci pneumatici. Totally seven sacci pneumatici were found in goose. Saccus thoracicus cranialis, saccus thoracicus caudalis and saccus abdominalis were in pair, however saccus cervicoclavicularis was single. It was determined that the saccus thoracicus cranialis and saccus thoracicus caudalis contained no diverticula and did not aerate any bones. It is first time that branching of the bronchi secundarii and relationship between branches of bronchi secundarii and sacci pneumatici in goose have been observed in the study

Kaz (Anser anser domesticus) solunum sisteminin makroanatomisi: Bronşlar ve hava keseleri

Abstract

Toplam 7 adet 4500-5000 g canlı ağırlığında ergin kaz (Anser anser domesticus)’ın kullanıldığı bu çalışmada bronchi ve hava keseleri makroanatomik olarak incelendi. Trachea’dan ayrılan sağ ve sol bronchus primarius’un akciğer dokusunda ilerlerken 4 adet bronchi mediodorsales (bmd), 10 adet bronchi medioventrales (bmv), 10 adet bronchi lateroventrales (blv) ve 25-30 adet bronchi laterodorsales (bld) olmak üzere dört grup bronchi secundarii verdiği saptandı. Bu bronchus’ların bir kısmının akciğerler, bir kısmının da hava keseleri ile bağlantılı olduğu tespit edildi. Kazda üç çift ve bir tek olmak üzere toplam yedi adet hava kesesinin varlığı belirlendi. Bunlardan çift olanların saccus thoracicus cranialis, saccus thoracicus caudalis ve saccus abdominalis olduğu, tek olanın ise saccus cervicoclavicularis olduğu saptandı. Hava keselerinden saccus thoracicus cranialis ve saccus thoracicus caudalis’in diverticulum içermediği ve hiçbir kemiği havalandırmadığı görüldü. Yapılan çalışmayla kazda ilk kez sekonder bronchus’ların dallanmaları, hava keseleri ve bunların birbirleriyle olan bağlantıları detaylı bir şekilde incelenmiştir
