Blood vessel

Blood vessels are part of the circulatory system and function to transport blood throughout humanoid bodies.

In 2373, a Pah-wraith possessing Keiko O'Brien threatened Miles O'Brien that by destroying even a tiny blood vessel in her brain it would destroy all of Keiko's memories and emotions if he didn't cooperate.
