Using the silicon (luminal cast plastination technique) for the lower respiratory tract in sheep as an alternative to cement

The lower respiratory tract of sheep was studied to determine the torsion and branching bronchial tree. system ruminants all living organisms is one most important organs in body that controls amount gas exchange between heart lungs through airways, it clear consists a narrow tube reaches extent lung tissue repercussions. He used silicon, water, acid, at room temperature, substance injected with an injection gun trachea pushed gently spread distribute parts moderate manual pressure. results showed mold shape branches bronchi solid anti-erosion very three-dimensional appearance, easy handle, store carry for study presentation purposes scientific museums, presentations as anatomical method large-scale teaching.
