Quizplus · Accepted Answer

The length of time different tissues can survive without oxygen varies. The brain will become hypoxic in 3 to 6 minutes. The other options are incorrect because submersion injuries do not cause atrophy to brain cells right away; submersion injuries also do not cause cellular lysis or necrosis to the brain.
