Speeding

What was the cause of my friends death?

So my friend got hit by a speeding car last night, and he died. I’ve been told he was covered in blood, was badly injured and didn’t die immediately..he probably died on his way to the hospital.
I’m just wondering what might caused his death..I really want to know! You guys obviously don’t know either but I want to know what you think?
What possibly could have happened inside his body??

First and formost CONDOLENCES TO YOU,
The cause of your friends death is Internal Bleeding here is a litle research about it:

Bleeding generally becomes dangerous, or even fatal, when it causes hypovolemia (low blood volume) or hypotension (low blood pressure). In these scenarios various mechanisms come into play to maintain the body’s homeostasis. These include the “retro-stress-relaxation” mechanism of cardiac muscle, the baroreceptor reflex and renal and endocrine responses such as the renin – angiotensin – aldosterone system (RAAS).

Certain diseases or medical conditions, such as haemophilia and low platelet count (thrombocytopenia), may increase the risk of bleeding or may allow otherwise minor bleeds to become health or life threatening. Anticoagulant medications such as warfarin can mimic the effects of haemophilia, preventing clotting and allowing free blood flow.

Death from bleeding can generally occur surprisingly quickly. This is because of ‘positive feedback’. An example of this is ‘cardiac repression’, when poor heart contraction depletes blood flow to the heart, causing even poorer heart contraction. This kind of effect causes death to occur more quickly than expected.
