What is the principle of biting the tongue?

Biting the tongue itself is not easy to cause direct death, mainly because this part of the tongue is rich in blood vessels and it is not easy to stop bleeding, so it causes excessive blood loss and death. In most cases, it will damage the lingual frenulum, leading to voice loss. Many causes of death are bleeding after biting your tongue, and blood will pour into the respiratory tract, causing suffocation and death. Some people may also die of hemorrhagic shock due to arterial rupture and massive bleeding.

Features of the tongue:

First, symmetry and freedom of movement. If the tongue itself is not deformed and there is no tumor at the base of the tongue, then the left and right sides of the tongue should be symmetrical and muscle activity will not be hindered.

Second, the tongue is pink. Normal people's tongues are pink, but some hairy tongues will be black with white spots on the surface. So a normal tongue should be pink, and not too bright red. Third, after the tongue is stretched out, you can see the complete tip of the tongue.
