minus-squarelyralycan@sh.itjust.workslinkfedilinkarrow-up7·1 month agoHoly shit. As someone who does not possess the knowledge, is blood white? The deoxygenated channels?
minus-squareMoonMelon@lemmy.mllinkfedilinkEnglisharrow-up22·1 month 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-up2·1 month 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.
