In an effort to procrastinate doing everything...okay, really simply to revise my material for next semester when I start working at hospitals (but the first one sounds less dorky D
...anyway...
In an effort to revise my material, I'm inviting each and every one of you to ask any questions you had on the human body (and mind). As long as it's medical, it can be pretty much anything- and I'll attempt to answer it as quickly as possible, hopefully off the top of my head.
Lol dirk, that's one way of putting it, but not really the whole story.
First, AIDS is in fact the end-stage syndrome of HIV, a lentivirus. AIDS is the name for the state where your T-cell count drops to pretty much zero.
This website will provide the main theories, including "guy getting jiggy with monkey".
Except that HIV isn't only an STD, it is blood-borne. Direct blood-blood transmission is probably more likely to get you infected than via sexual activity.
is deoxygenised(i think thats what they say....?) blood really blue?
and here is something i want to know about: if vomiting is just a defence to expel anything harmful eaten, why do some people puke when they are in rollar costers, fast rides, etc?
I answered this on page, uh...18? Around there, I think. The short answer is "we don't exactly know" :P
i want to know how painfull ebola would be.
No idea how painful it is, but the virulent, pathological strains (Zaire, Malinga...I'm not sure that's the right spelling) are extremely nasty. You feel absolutely horrible, with nausea and headache (initial symptoms are frequently mistaken for the flu). Then you start vomiting and after a while it's bloody and dark and gluggy. This is because you're actually vomiting up your stomach lining, so after a while you start feeling really cramped in there. Then your organs in general start breaking down and your eyes go bloodshot and you just sit there feeling like you're going to pass out, and when you do, you pretty much explode blood from all your orifices and collapse.
The worst part of Ebola is not the pain. It's not even the projectile vomiting your insides all over the place uncontrollably. It is when the tissues of your heart start breaking down and you get palpitations, and with that, patients, both survivors and casualties alike (yes...people do survive Ebola), report a gripping fear unlike any other.
The idea of this 'crashing' is because Ebola is blood-borne, so it seems to try to make the process of breakdown as spectacular as possible so as to improve chances of transmission. Believe it or not, even if you organs get turned to mush, they can actually recover from the damage by regrowing new lining, but this too is an unpleasant process and patients who are recovering from Ebola are generally in constant pain and grumpy as all hell.
Gross huh.
Ya, I thought it all started out in Africa, where the men/women Violated monkeys, lol, that's what they told me in school.
Ah, sensationalism. Crazy stories always get more attention :P
Though I'd have to give it a thought...would it be possible to get HIV from 'violating' a monkey? I'd say yes.
DD, I'll get to your question on stinging pain later on.
is deoxygenised(i think thats what they say....?) blood really blue?
Not quite blue but a dull, darker red. You could say that it was tinted blue/brown, as opposed to arterial blood's rich crimson red.
However your veins appear blue under your skin, yes.
if vomiting is just a defence to expel anything harmful eaten, why do some people puke when they are in rollar costers, fast rides, etc?
Vomiting really isn't just a defense with a function, it is also a byproduct of other functions. Vomiting is generally stimulated via certain cranial nerves (well, mainly CNX: the vagus, or so I think), and there are multiple pathways to this.
* On rollercoasters or fast rides, your vestibulocochlear system (the loops in your ear responsible for your balance) can go all crazy and disoriented and this in itself leads to nausea and the overwhelming desire to puke.
* When one is really scared, one can also wish to puke because one of the effects of adrenaline is to encourage emptying your gastrointestinal tract entirely so that your system doesn't have to concern itself with that, or direct blood to it (exercise after eating gives you a stitch and cramping for this reason).
* If your stomach is really stuffed to overfull, not necessarily from poisoning, there's a chance you may puke. One of the reasons drinking copious amounts of milk is a bad idea is because milk exerts a very high osmotic pressure- it will pull water from your body into the stomach strongly, causing it to swell up. And that will make you puke too :P
strop this is a reply to the ebola answer. that was a really answer. i kinda already knew. im reading this book about the filoviruses called the HOT ZONE u should read it. it tals all about marburgh ebola Zairre ebola mellinga and alot of other strains, like the cardinal strain
