The AD33 crucifixion detail in Judea

[starman2012]

When the spear was thrust into Christ's side, blood and "water" flowed out. The lungs were also filling with tissue fluid, and a form of 'auto-drowning' was also a contributary factor in eventual death.

Dunno if the spear thrust is historically accurate. Strange that the synoptics don't mention it. Of the four canonical gospels, the gospel of john is considered the least historically reliable.
