I have always wondered why I was taught in school for so long and it turns out that apparently lots of other people were taught this too.

The only reason I can think if that we were raight that blood in the body is blue is because our veins look blue. But does anyone know where that myth came from or why kids are still being taught this today?

    “We” weren’t because we had competent teachers. I do not know a single soul who was taught nonsense like this.

        Were you? Or were you not quite paying attention and misinterpreted the picture while not listening to the teacher properly?

        I remember the picture with the blue veins. I also remember being taught that blood goes from dark red to bright pink, depending on oxygenation.

          Nope, I was absolutely taught that blood in the body is blue until it reaches oxygen. Was paying perfect attention and that is what I was taught
