Why are there arteries in the brain?

This forum made possible through the generous support of SDN members, donors, and sponsors. Thank you.
You have blood vessels in your brain for the same reason you have blood vessels in every tissue of your body: to transport oxygen/CO2 and nutrients/waste products.

Perhaps, you should choke yourself for a little bit, that should clear up why you need blood supply to your brain :meanie:

Maybe you should read about the blood-brain barrier. I think that is where you are confused.

TROLL. There is no way you want to become a physician and you do not understand the concept of why the most important organ in the body needs blood. Im not buying it... Your a troll
 
Wow, you guys must be fun at parties...

Obviously I'm not an MD, but still a graduate student. How does the brain tissue receive the oxygen from the vessels without the blood destroying the brain tissue? I am studying traumatic brain injuries and necrosis occurs when blood spills into the surrounding brain tissue.

Really? 🙄

Oxygen is released by the hemoglobin and is able to cross the blood-brain barrier, however, RBCs do not cross.
 
It takes all kinds...

But if RBCs don't cross the BBB, then what about hemorrhages?

You're studying trauma and you don't know that a hemorrhage is a break in a blood vessel and the blood brain barrier?

Dude, you absolutely do not belong in graduate school, or you have too much free time to be playing a bumbling ***** on the internet.
 
I'm in grad school, and I learned a lot from this thread 😳

I've had a hell of a lot of biochem/genetics, but only half a semester of physiology in my life...
 
I'm an MBA douchebag. I learn about finances and how to interact with people properly. This was obviously outside my realm, which is a tiny sliver of life. And I'm not the one with thousands of posts on an internet message board and calls himself rHinO.

Get off the internet and go outside. You are probably fat. Like a rHinO.

Thanks for the link. That's all I was looking for.

When you say you are a graduate student studying traumatic brain injuries, absolutely nobody would think you were an MBA... instead we think you're either BSing or a complete idiot. So excuse me if I thought you were an effing ***** 😎.

BTW, you are welcome for answering your question... which you could have found by using google.

Very mature. Clearly your classes in learning to interact with people properly are paying off.

Hmmm....carbun dioxide and oxygen? Sounds like some wizard talk to me.

Hmm. I have been called a sorceress before, but that was pertaining to my beer pong capabilities. Wait a second... Why the **** do we have kidneys? Or a liver?? I better go do some more research.

You call yourself a med student? The kidneys are for excreting concentrated evil and the liver is like a workshop for farts. READ A BOOK!!
 
I'm lol'ing at the fact that this is even a serious question. Already been answered, but...

Oxygen is SMALL and diffuses through your blood brain barrier. It goes through to all parts of the brain through the cerebrospinal fluid which is basically devoid of anything but some water and sodium.

Obvious troll is obvious
 
So where can I get a MBA with a concentration in brain damage? Sounds absolutely marketable!
 
Wow, you guys are being absolutely too harsh to some person just wanting to learn some facts about the brain.. instead of mocking the person for asking a question ("how can you be a grad/physician if you don't know.."), why don't you just simply answer or send a link to help.

In my view, one of the most important qualities in physicians is being able to educate others.. if you can't do that, then maybe YOU don't belong here.

Anyway, I thought it was a legit question, OP.. blood cells are toxic to neurons if they're in direct contact with them, but since a protective layer envelopes the brain and arteries (ex. pia mater, an inner membrane, rich with arteries), blood doesn't cross through. Also the arteries' cells are tightly connected, so only small molecules such as oxygen and glucose can pass (aka BBB).

You're new to SDN, so you don't get it yet.

Anyway, you know what else is an important quality of a physician, which frankly is more important than being an educator? The ability to GO FIND AN ANSWER. "Oh ****, my patient has purple pee? I wonder what disease that's associated with ... Let me go to a reference book and/or internet and see what I can find."

If you spend the time to register an account and post questions and responses, surely you can type it into google?

Hence the lack of mercy.
