Why is it that when they cut you open for surgery, blood doesn’t come pouring out, but then if you cut yourself open you’d bleed a lot and then die? :o
Ask Sin.
That would depend on where you cut yourself. If you hit a major vein or artery you’d bleed out pretty quickly.
In surgery surgeons know enough not to sever any major blood vessels if they can help it.
Of course you bleed.
However, a skilled surgeon won’t cut major vessels that will cause you to bleed profusely. You can, for example, removed a tumor from a lung, even a large portion of the lung, without doing a blood transfusion if you’re good enough. Remember, for there to be bleeding, there has to be blood vessels and when you cut through an area, you try to avoid needlessly cutting open vessels that will bleed. If bleeding wasn’t controlled, you’d have major problems because while you have a lot of water on reserve, a rapid loss in fluid can be dangerous. Also, if you aren’t a hemophiliac, your blood will clot at the sites where the cuts occured, helping control the bleeding in addition to the suction and padding which the assisting staff will provide to keep the area free of fluids as much as possible. Finally, you can also tie off vessels so that if you need to cut a big vessel like to remove a lobe of a lung, the opening will be clogged and the blood will merely be diverted elsewhere.
Ooh, this stuff makes me squeemish!
Ah! Also, what’s a good medical school that isn’t very expensive? And that hard to get into. :x
Still, even during short surgery, often a blood transfusion is required to replace lost blood.
Depends on what kind of surgey you’re talking about. I’ve had surgeries and never needed blood transfusions because the cuts were ridiculously small.
Think of wisdom teeth removal (I’ve had it), I didn’t need a transfusion for that, and it’s one of the most common surgeries out there.
Getting your wisdom teeth removed is fun, I think. The only part I really remember between waking up from getting them pulled and them waking up the next day was standing in my kitchen sink, laughing maniacally while spraying blood and the little swab things everywhere.
Question: Why do I get the creeping feeling that “defectivesonydvd” is someone I don’t want anywhere near a medical school, much less a hospital?
It’s easy to say that when he’s like 12 years old >:E
Hey! NOT COOL! I’m hecka smart! And I’m class rank 1 in my anatomy and physio class, that doesn’t make me a surgeon but it can somedaaaay. :booster:
Just out of curiosity, how old ARE you, anyway?
I like all these fun random facts about bio- threads lately. <3
What about for surgery to remove the appendix?
Waking up from wisdom tooth surgery? They had to put you out, Lanyx? Wuss.
The mouth is the fastest healing part of the body.
You don’t have to worry as much about cutting a vein, because the big ones tend to be in the center of your body near the heart where they all merge together. It’s the arteries, the vessels traveling away from the heart, that you need to be careful of. Those are the ones that will spurt blood if you cut them. Fortunately, they tend to be a bit deeper in, so you’d have to cut deeper, usually, to break one.
Well, my point still stands. He’s not Doogie Howser, is he?
I’m a 16-year-old GIRL, not a 12-year-old BOY! And I’ll be 17 in three months! O;;,…,;;O
See?
If the teeth are growing sideways in your mouth, it’s advisable to get knocked out. If they’re growing in rather normally, you only need to get numbed.
