It’s often said that despite humanity’s many conflicts, we all bleed the same blood. It’s a nice thought, but not quite accurate. In fact, our blood comes in a few different varieties. Natalie S. Hodge defines the four major blood types and sheds light on why some bloods can mix while others cannot.

Lesson by Natalie S. Hodge, animation by Brad Purnell.

How come the proportion of O blood type is way higher than A, B or AB? I mean, since it is recessive, shouldn't it be rare?
Tyler3978 Prije 3 dana
Just because it's recessive doesn't mean it's rare. Having 5 fingers is a recessive trait, while having 6 is dominant

Addison Anderson, you are excellent. I've known my blood type since a college biology lab but I am sure it should be on every birth certificate, it has been ours since we were in the womb. My Blood Type A+ is important to know...A's have alkaline stomachs and cannot tolerate acids. Learn about the particulars...and you won't succumb to purple pills. To thine own self be true.

I literally want to know my blood type but I don’t know how to find out. I already asked my parents so many times what it is, but they said they’re not sure if it was O or B. It’s not on my baby book or birth certificate, not on any blood test forms etc. I want to ask for a blood type test kit but they’ll probably be like “Why would you need one?” or “You asked too many times”😢

The video makes distinctions between blood types, but fails to answer the actual question posed. Why is it important to have different blood types at all. Why do we need different blood types, and why did evolution allow for different blood types. My guess is that some blood types are better at processing meat vs vegetables or survive in different climates...

Sergio Prije mjesec
WTF? There is no O type, it's 0 type! (zero type) It's not a type of blood, it's the absence of antigen, that's why it's zero and no O.
if the o blood types doesnot have antigens than doesnot they get attacked by wbc?and why every children of same parents doesnot have the same blood type?

Viewers do not use this video as a reference for facts. There's incorrect information in this video. I'll list one; there are others. Its amazing how they even put up a link for the "full lesson" what is there to learn if there is miss information. My child is O+ the mother is A- and I am O+ according to there miss information the O should of been canceled out by the A; resulting in my child being either A -/+.
