i always thought blood was red. my son came home one day and told me that he learned in school that our blood is really blue before it touches the outside. how are we supposed to support our schools if they cant even provide our children with correct info. im sticking with the blood being red. my son is very smart so sometimes i learn new things from him. things can get quite confusing.

Blood is not blue whether it's oxygenated or not. your confusion may come from the fact that many text books illustrate blood as being blue before it's oxygenated as they follow it's path through our vasculature. I agree with the other people who offered answers that venous blood is darker red and arterial is bright red.

First thing: Blood is *never* blue. Blood is described as dark red (venous) or bright red (arterial). Our veins look blue because we are looking at them *through* our skin. The blood inside them is dark red and it doesn't reflect light very well. The blood you see when you get hurt is usually venous blood.

No, your blood is red. Think of it this way. When you get your blood drawn does it get exposed to oxygen? I think not. It gets taken from you arm thru a needle to a vacuum tube.

Blood is always red, just different colors of red. It only appears blue because you're viewing it through your skin.
