Thanks!

4 quarts is about right for an "average" human, and of course here is the obligatory link with more than you ever wanted to know about blood.

You know, I've heard the the human heart has enough pressure to squirt blood 30 feet from the body.

And 2 gallons of blood does sound like a lot. Maybe it's 8 pints, which is one gallon...that seems more likely.

I'm confused, that link says that type AB is the universal donor. I thought O- was the universal donor because the red blood cells don't have the um...receptor things on them. And then AB+ (which is my blood type) can take any blood type, because it has the A identifier, B identifier, and O doesn't have an identifier.

4 pints???

Hell, when you donate blood they take a pint. I would find it hard to believe they would take a fourth of someone's blood at one time!

I'm thinking the 8 quarts is closer to reality for the average person.

IHadAPheo seems to have the best grip on this. If I understand righ, he has reason to, too  Big grin. Anywho - 4 quarts sounds about right, and yeah they do take 1 pint so 4 pints sounds way to low.

Here is a bit more info from http://www.americasblood.org/index.cfm?fuseaction=display.showPage&pageID=13#universal_blood_type



Type O negative is the universal donor and can give blood to any other blood type. 8% of the U.S. population has blood type O negative.

AB positive is the universal recipient and can receive blood from any other blood type. 2.5% of the U.S. population has blood type AB positive.

As to the distance blood can "squirt" the personal best that I have been a target of is about 6' or 2 meters during a severed radial artery repair (just a reminder, do not put your arm through a broken window)

While the best shot of activated charcoal during an over dose treatment was about 9' or 2.9 meters to our treatment room ceiling. Don't even ask me about retrieving foreign items from certain bodily cavities

The average person has about 8 pints of blood in his/her body. I donate blood 3-4 times a year because I have a rare blood type (AB+). A pint of blood is also call a "unit" in the US medical field. So if you choose to donate, they can't take more than a pint (unit). Your body usually replace the taken blood within 48 hours. And you shouldn't donate again until 6-8 weeks later. When I say 8 pints for the average person, I mean an average-sized adult. Some bigger & petite adults will have more or less in their system. Children are different obviously. Also it's 2 pints to a quart, and 4 quarts to a gallon, in US liquid measurements. Regards.

My dad was O- and the Red Cross used to hunt him down. heh heh. When he was in the Marines, he donated far too frequently than recommened. He had all sort of 'gallon' pins from them. Ironically, later in his life, he needed two transfusions from internal bleeding.

I have a boring B+ blood type. I used to donate all the time, but last time they rejected me because of hypertension.

First time I ever donated, the Red Cross made it difficult. We had just been on a mission trip to Mexico earlier that year, and we were out in the the sticks...which means none of the places we went to were in their book of Mexican cities (the ones that are safe, like Moneterrey, and the ones that aren't, like Mexico City). Passed that hurdle, then the nurse took my blood pressure. 160/108! Way, way off. I'm not hugely muscled or anything, but I have a good sized arm, and the cuff was a little small for me. She retook it with a different cuff and it was 120/80, which is normal for me. And we quickly cleared up the Hepatitis A vaccine that I'd had more than 6 weeks prior was not a problem. So finaly I got to give for the first time, and it went fine. That was at school during my senior year.

I gave again this year, in the Transylvania Bowl. It's a competition that Mississippi State, Ole Miss, and Southern Miss have with each other. We haven't won it in about 5 years, however, because MSU laws only allow donor services to take blood on campus 1 day a month. The competition goes for 3 days, and they're on campus all the time at Ole Miss. Not so at State. I learned that time that it's stupid to forget to eat breakfast before you go give, though. That one really took the wind out of me.

And IHadaPheo, maybe the 30 feet figure wasn't for going straight up against gravity? Nine feet is still dang impressive, however.

I have O+, used to donate until I found each time my blood pressure would bottom out and I'd start loosing my vision and shivering towards the end of the donation. Freaky stuff.

Uh, hello?! The bigger you are, the more *fluids*, not necessarily blood, you have in your body. I really don't think Mini Me can fit that much blood into his circulatory system.

I heard it was like 60 gallons (I'm probably sure it was 6 liters) but whoever I heard it from, is sure a real idiot...
