Is all blood red?

[TheWizard]

Ok is all blood red. Do bugs have different color blood?

[Whisper]

As far as I know yea when blood has oxygen in it its red
When there isn't any oxygen in it its blue

Thats why when you look at your wrists the veins are blue not red

....I've had a facination with blood for awhile

[Kiros]

Well, when human blood has oxygen, it's usually bright red. When it has low oxygen, it's a very dark red, and when it has none, it can appear to be blue or black.

Though an insect's blood can be a different color, such as green or yellow. It depends on the DNA and how their blood cells are constructed.

j/w is that why our veins are blue, cos the blood is blue but when we bleed tis red?

[Kiros]

Our viens appear blue because there is a lack of pure oxygen. This causes the blood to be extremely dark, or blue in some cases. When a vien is cut open, the blood flows out and absorbs the fresh, pure oxygen and becomes bright read. How bright/dark your blood is depends on the amounts of iron and whatnot in your blood.

i swore when we were dissecting frogs last year that the blood wasnt red..i think the blood was blue or white..i dont rele remember

[redcar]

u disect frogs? thats disguisting i would refuse point blank to do that.

[kolte]

i disected a squid, twas interesting.

[redcar]

omg u did? the poor squid

[kolte]

it was allready dead

[redcar]

still, poor squid :(

[Dante]

if it was dead already, whats the matter?...and yes blood is red when exposed to oxygen...i think cody and kiros covered it basically

[redcar]

if it was dead already, whats the matter?

i ahve a thing when it comes to dead things i dont them to begin with and i dont like the idea of them being, for want of a better word, interferred with. i know its all in the name of education and all that jazz i just dont like it.

[Ravenous]

We never got to do disection :(
Yeah Cody and Kiros got this one really.

[kolte]

if I take biology in college, I may get to scramble a frogs brain by incerting a needle threw its skull and destroying the brain in a stritigic place. and then when I open the frog, all the insides are still working, neat eh?

wat if you didnt want to do it, like you were a conscientious objector?

[<-Dying_to_Live->]

Our viens appear blue because there is a lack of pure oxygen

oh, so u mean like every single moment of your life?

[ThePhantom]

Ive disected a frog and a squid. . i dont remember the squid having ANY blood . . and the frog (as mcoupe said) didnt have red blood. . . if that was the case it would of been a bit graphical . .ant remember exactley color the blood was for the frog

[Kiros]

Our viens appear blue because there is a lack of pure oxygen

oh, so u mean like every single moment of your life?

So what are you saying? Yes, everyone has a lack of oxygen in the blood inside their viens at every single moment of their life. Is that hard to understand... or am I missing something?

[<-Dying_to_Live->]

no i was just clarifying, sheesh

[Kiros]

Well now it's clear, isn't it? :)

[nwshc]

Well sometimes they are not dead.
We are going to be disecting frogs soon, and while its alive, kindof
you stick a needle in the neck which sortof kills the frog but all the organs and shit stay going. The frog should feel no pain.

omg that is like so fucking disguisting, wat if you dont want to do it?

[nwshc]

erm... I guess you watch. There are papers you have to do so you have to at least look. Or get a zero or something.

[redcar]

i think that is so wrong though. poor little frogs.

[AC.wAkeBoArDin.06]

ok look

Blood in ur body that is in VEINS is BLUE... because its going back to ur lungs to get Oxygen.... once it gets oxygen its red... this is ARTERYS.... u have blue veins on ur wrist and some red vains anywhere on ur body.... just look and im sure ull be able to find one somewhere.... its just ur body uses soo much oxygen... blue seems to be everywhere... once that blue blood hits the air... it turns red because of it touching the O2 in the air....

Some bugs have clear blood and some have black blood....

[TheWizard]

But what about bugs. If you smash they its yucky yellow. So do they have yellow blood?

[Kiros]

Kind of, yes. Like I explained before, an insect's DNA is far different from ours, so their blood would be different too. Though for the most part, a bug's blood is somewhat translucent while other fluids in it are yellowish. That's why when you smash a bug, it looks that yucky yellow. Get it? :)
