...when we are subjected to an ordeal or shocking news?
I presume that the blood is going to other parts of the body, the opposite of what happens when we are embarrassed, why?

losing the colour in our face is due to our body's fight or flight response which kicks in as soon as we are under threat or suffering from a type of stress. it induces our body to shut down all peripheral functions and optimizes protection of the internal organs. cappilliaries constrict thus reducing blood flow leading to the paleness of the skin. a racing heart and slight trembles is the result of adrenaline being pumped into our bloodstream from adrenal glands. all of these reactions are the result of thousands of years of evolution designed to help our race survive. fight or flight response is an involuntary action and im sure u have read enough by now!!!!

So Chief...what is it you are saying ??? I will tell you all how I feel... The Legion is correct in what it says... and how it says it... The disclaimer only says that it is their View... But then they have about a Million Members that have "Been There, Done That"... Personally I feel "ALL" illegals from any country should be rounded up and sent packing... I am not a member of the American Legion... but I am a Legal immigrant that served two tours in Vietnam and became a US Citizen. What the American people fail to understand is even the amount of Marriage VISA's that were granted 60% turned out to be Fraudulent and the next 30% were divorced after the two year Conditional VISA was up and they had been granted a permanent one. Can see the Second American revolution just around the corner...

Your brain receives the signal that you have received a shock in which case the brain will send the blood rushing to the vital organs, i.e. heart & brain in order to keep them functioning hence the blood draining from your face.

When you are going into shock the colour drains from your face cause it is needed somewhere else in your body and also because you blood sugar level has dropped so suddenely!!!!!!!!! Hope that helps!!!!!!!!!!

the blood drains from the face when your body is wanting it in other places most probably your legs if your running from a ghost!
But when it goes to your cheeks it because your feeling hot and flustered and the quickest way to get rid of heat out the blood is to go to the face cappeliers and this makes you glow a reddy pink
i hope thisz helps

I think it's a drop in blood pressure that does it.

its called 'fight or flight' and its controlled by your autonomic nervous system, blood goes to other parts of your body, e.g. myscles, heart etc so you can either run away or stay and fight it!
