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?
I wasn’t taught that in school.
“We” weren’t because we had competent teachers. I do not know a single soul who was taught nonsense like this.
Well, I was taught this, so there🤷🏾♀️
I do love the level of gaslighting in this thread
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
you were actually taught that?? for the love of Snoopy
Yes, I was actually taught that blood in the body is blue until it reaches oxygen
I was definitely told this as a kid, but I don’t remember being taught it in school.
It’s completely possible a Latin teacher or a history teacher told me too but it wasn’t a part of the curriculum.
Afaik, nobody knows where/when the myth started because it started organically, rather than being something like bumblebees not being aerodynamically sound, where there was poorly explained information that got spread from that point.
The most popular theory of the origin is that since veins look blue, and thus were drawn as such in anatomy illustrations, the idea got spread through wide ranging multi point origins. I’ve seen people argue for the veins looking blue as the genesis, with the idea being that someone asked why blue veins ran red when cut. But I’ve seen it argued that it wasn’t until the illustrations came along and faulty information was needed to explain that that it spread far enough to actually be taught by people that should have known better (like some folks, I ran into the idea in jr high, knew it was wrong because of family with medical training, and got in trouble for trying to say so).
But I have looked a few times over the years to see if I could run down a definitive origin story, and never have. Mind you, me looking involved searching for articles about it, rather than trying to run down historical references direct because I don’t have that kind of access.
You had some dumbass teachers.
Some teachers have no idea about things and still try to teach them. They aren’t different from other people there.
We were taught a lot of stupid shit in elementary school, because the teacher was a crank and proud of it. I remember vividly how he tried to explain the density anomaly of water (to ten year olds) by saying that atoms in solid objects move faster than in liquids and therefore need more space. I didn’t believe one word of it.
I remember my second grade teacher saying that stars aren’t actually suns, they are just specs of light in the sky, and they don’t get much bigger once you get close up to them. In hindsight I’m baffled that someone with such a simplistic worldview actually managed to meet the educational requirements for being a teacher.
Your school was beyond garbage. In my school they explained to me how hemoglobin works and why it’s red. (it’s because of Iron atom that captures specific wavelengths)
where was your school?
The Midwest.
default country of course
Huh?
Nvm, whatevs🙄😒
Did you go to school during a period of time where there wasn’t access to information on the Internet? Old wives’ tales had more legs back in the day because you’d have to visit a library and open a card catalog to disprove them.
Think you were on the wrong school or maybe planet
Yeah, no.
Then it can only be the country , murica
