There are multiple sites that a tortoise can be bled from. The best site is the jugular veins as
there is minimal risk of dilution of the blood with lymph from this site. The jugular vein runs from the tympanic membrane
to the dorsal aspect of the neck at the thoracic inlet. Other sites to consider include the subcarapacial sinus which lies
underneath the carapace just behind the junction where the skin of the dorsal neck meets the shell. There is a lymph sinus
in front of the sinus and dilution is possible. Other sites that can be used include the dorsal tail vein.
