Your husband died of a massive heart attack and he kept biting his tongue which also appeared enlarged why?

When someone experiences a cardiac arrest or heart attack, it is common for them to exhibit certain reflexive actions such as biting their tongue due to involuntary muscle contractions and loss of consciousness. In some cases, the tongue may also protrude or appear enlarged because the muscles in the face, neck, and jaw lose control due to the interruption of blood flow to the brain.
