rhexisn.

Brit.

/ˈrɛksɪs/, U.S.

/ˈrɛksəs/

Forms: Middle English rixis, 1600s– rhexis.

Origin: A borrowing from Latin. Etymon: Latin rhexis.

Etymology: < post-classical Latin rhexis bloodletting, rupture of an organ or tissue (from 13th cent. in British sources as rixis ) < ancient Greek ῥῆξις action or fact of breaking or bursting, breaking forth, discharge, especially of blood < the stem of ῥηγνύναι to break (see -rrhagia comb. form) + -σις -sis suffix.

1. Medicine. Rupture of an organ or tissue, esp. of a blood vessel; haemorrhage or extravasation of blood resulting from such rupture; an instance of this.
