minus-squarelyralycan@sh.itjust.workslinkfedilinkarrow-up5·5 days agoHoly shit. As someone who does not possess the knowledge, is blood white? The deoxygenated channels?
minus-squareLydia_K@lemmy.worldlinkfedilinkarrow-up4·5 days agoThat one guy in Carbon Creek is an outlier and should not be counted.
minus-squareMoonMelon@lemmy.mllinkfedilinkEnglisharrow-up15·5 days agoDeoxygenated, venous blood is dark red. Oxygenated, arterial blood is bright red. I was taught the “blood is blue” myth also. My mom was livid, since her job involved drawing lots of blood, starting IVs etc.
minus-squareteyrnon@sh.itjust.worksBanned from communitylinkfedilinkarrow-up2·4 days agoI called bullshit from the start on that. If it was true, that blood turned red when it touched oxygen, then pulling blood from the vein in a needle would be blue. Teachers told me to shut up. It’s such a stupid theory, knowing what we knew.
minus-squareanomnom@sh.itjust.workslinkfedilinkEnglisharrow-up5·5 days agoPlasma separated from red blood cells is sorta yellowish beige. At least in IV bags.
