Specific knowledge of the normal anatomy of individual species is important. The absence of an epiglottis facilitates tracheoscopy but the glottis is capable of spasm and can be easily damaged. The air sac and extensive rib cage of snakes means that insufflation is not always necessary. The anatomy of the thin, sac-like, lung means that it can be easily punctured. The long, relatively straight gastrointestinal tract facilitates examination. The vent may permit access to the colon and urinary and reproductive openings.
