The viscera is the collection of organs located inside the torso, and this calf viscera contains a heart, lung pair, and trachea all connected. Although the trachea is the throat tube, it closely resembles the intestines. The calf viscera varies in size, but is roughly the same size as a full grown person. The viscera is embalmed with alcohol and propylene glycol and is hygienic and safe to handle. Comes in a vacuum sealed bag and lasts for weeks once opened. Also available in a 2 gallon specimen jar of humectant for an extra charge. When doing a realistic autopsy or dissection scene, nothing beats using real organs.
