Blood Types

[@sarahann8856]

you taught me more in this 10 minute video than my teacher did in 2 weeks

[@tikamidun3582]

True!!!

[@alika4681]

YEP

[@connersmith409]

Literally.... Same

[@tirex2224]

Wtf lol

[@raz0rcarich99]

I swear this exact comment exists on every youtube lesson ever

[@OilersLBA]

Again, Bozeman Science saving me in biology.. As a guy studying Pscyhology, and whom has no experience with biology what so ever I simply could not have done without you! And, also, I learn much better watching your videos than listening to lectures. Thank you, Mr. Andersen!

[@NaviTheKitty]

You taught me this stuff in 10 minutes and i fully understand when my teacher taught it in a week and i had no clue what was going on thank you savior

[@backstreetfan2887]

Mr. Anderson refers to an "A protein" however the A, B, and O antigens are definitely carbohydrates, not protein. Some people in the comments are saying "it is a glycoprotein" however I checked my molecular biology and biochemistry textbooks and they say that the oligosaccharide can be attached to a lipid or a protein. The gene involved in ABO blood types codes for an enzyme (glycosyltransferase) which can add a monosaccharide to the O antigen. If you have the A allele you have the transferase that adds N-acetylgalactosamine to the O antigen. If you have a B allele you have a transferase that adds galactose to the O antigen. People with AB blood type have both transferases and therefore both A antigen and B antigen.

I love this guy. Mr. Andersen...please be my college professor! Or at least show my current instructors how to teach students better!

[@altair2594]

i always get here when im lost in medical biology.. thank you so much!!

[@brandontran4929]

Watched this video in AP Bio, now i'm back to watch it during Pharmacy School

[@charlovespink]

I couldn't do my assignments without your videos!

[@floodbeforethestorm]

Thank you for making these videos and being a better teacher than my actual biology teacher. I learn more from your videos than a week of class

[@RDRWindwaker]

Your high school teaches should be thankful for having you, Paul. I learned more in ten minutes than I did in an entire lecture from my biology professor

Thanks, what a legend this man just made my day

[@Bozemanscience1]

Check out the AP Biology Lab playlist. It is near the bottom. Hope this helps.

[@tusharjhakra8347]

nice video sir....but can you also explain Bombay blood group. It would be of great help

[@xiiixiiih.16]

😅thank you

[@amrutvani2]

Kindly check ABO system antigens are not proteins but oligosaccharides ( carbohydrates) while Rh antigens are proteins.

[@aversion91]

Mr Anderson, You are doing a wonderful work....i am sure it is helping many people like it is helping me........

[@arianarice4911]

Thank you!!! That clears the whole antibody vs antigen thing right up!

[@boogieman3498]

This was extremely helpful. Im studying for my PBMT (Perioperative blood management technologist) test and this was so confusing for me to understand when I saw it in my book. This video made it very simple. Thank you! Is there any other videos you would recommend that would be helpful to my studies?

[@schoolwithapril9531]

Thank you! I am doing a blood typing lab today in class and I wanted to explain this better to my kids.

[@lyr5436]

Probably my favourite of all your great videos. Thank you very much for making such a brilliant series of videos.

[@jessyc6779]

Thanks! I have a quiz tomorrow. The chapter is literally named after Mendell, but it goes way deeper than that. So this was a great review. :)

[@supergbonin]

Better than my teacher could ever teach it. Thank you

[@sumavishy08]

So nicely explained for people from non-biology background......My 8 yr. old could grasp it clearly. Thanks....

[@Starquasia232]

You have been so much help this semester, thank you dearly. You make bio fun and especially with the colored images you use

[@annsmahboob3495]

Sat biology book was really vague, this cleared it out very well. Thank you. Already subscribed.

[@diodio520]

What a wonderful explanation! Great recap. Thanks Mr Anderson

[@EmeraldButHeIsIRL]

Awesome dude my teacher only showed part of this in school so I came to watch this

[@CreativeSoul101]

This helped me understand the punnet square more which I have a hard time understanding some aspects of

[@eleabell7607]

Glad I made someone smile.

[@karraht.304]

THAANK YOU MR.ANDERSON!!!!!!!!!!!!!!!! YOU HELP THE WORLD

[@aristotelis67]

I use these videos for teaching basic genetics at the university! Great explanations! Thanks so much...

They are really great medical information or even public! It was amazing and helpful. Thank u..

[@wallnut6666]

At 8:43 you said during the 1st pregnancy nothing really happened because we're only sending antibodies in one direction from the mother to the baby. Not sure you actually said what you meant to say there, because if the mom were sending antibodies to the baby that would cause problems. But the mother doesn't have any antibodies to send to that first baby yet (if she's never been exposed to Rh previously). It isn't until her blood mixes with that first baby's Rh positive blood, (mainly during birth and through the placenta etc), that any anti-RH antibodies will even start to develop. And they take some time do so. So, as you say, there most likely won't be any problems with the first pregnancy. But then it's during the second pregnancy that the problems could arise if that baby is also Rh positive because by then she already has anti-Rh antibodies fully developed in her blood plasma. That's why they give the RhoAM injection to Rh negative mothers during the first pregnancy to prevent the antibodies from being produced.

[@shoutitallloud]

Could you please explain what if mother has O blood and baby has A (or B) blood type. Shouldn't mothers antibodies be attacking baby blood cells? This also applies to mother A and baby B. No?

[@mellygirl23]

Another helpful video from Prof. Andersen :)

[@anamaldonado1377]

I really like the way you explain !! You are helping me a lot with my courses. Thanks

[@brianoneill3887]

At time frame 8:13, the captions say, "If they're both heterozygous," which is the correct description of the parents. Paul Anderson misspeaks and states, "if they're both homozygous." I'm just pointing that out as a speaking error, so people don't get confused.

[@mexiphil]

this is so clearly explained and helpful. thank you! this helped me on the mcat.

[@shobhathapa4872]

Really sir understood in short very clear 😁👍🙌🙌🙌

[@AimanM]

That was very helpful. I loved this topic. You make our all the way more interesting. I wish I was in your class.

[@CrazyGuyVideos2005]

it's also very helpful if you really wanna make sure a fictional character can't get a blood transfusion.

[@TheSteffyramlal]

I love this haha

[@rshngmz12]

Your videos are becoming addictive

[@christinatorres4872]

you are truly a blessing!!!! thanks so much your videos are FANTASTIC!!!!!!

[@Alvarez3230]

Started learning this in human anatomy. So interesting

[@eoz640]

Thank you :) . I feel very relieved now i can understand this properly for my nursing exams :)

[@KatieFerraro1]

Great way to explain this topic. Thanks for sharing

[@JonesyYaoi]

Thanks a million for these videos they are amazing. Very helpful.

[@yvetteantoine2653]

so clearly explained- thank you!!

[@markandrews1219]

Thank you for such an easy to follow explanation. It would be great if you can do an expansion of this topic on the 33 blood types and potentially one on the evolution of blood types...

[@peterjl1381]

Very helpful and illustrative video! Thank you very much

[@raulj5313]

You are the best! One in a million!

[@coulouista6318]

finally i understood these!! had these 4 tomorows exam !!!

Wow ! Would have loved to have had you as a teacher , thank you , very interesting

[@sinathleang]

Omg thank you sooo much for posting this video!!

[@hanniedark]

Your videos are so helpful! you are a great teacher :)

[@gundhamtanaka8006]

Thanks a lot! Ir seems so easy and simple now!

[@kavatea2970]

Please also explain , which blood group can receive what type RBC or what type of plasma (rather saying blood alone , there is huge difference)

[@jaouadrahouani4975]

I dont understand what is happening from 04:13 onwards about the genotypes? Whatis the logic thats being used to come up with those block schemes?

[@coffee-xg6my]

What he's showing is the different possible combinations of dominate and recessive genotypes in the Punnett square. Each parent has two alleles and one of those alleles from one parent is used to make a child by combining with one of the alleles from the other parent. The two alleles of each parent are shown on the outside edges of the squares on those "block schemes" that you are referring to. The upper case I's are the A and B genotypes which are dominate. The lower case i's are the type O which is recessive. So, anytime the A or the B is combined with an O, the resulting blood type (shown inside the squares), is always going to end up being an A or B blood type because A and B dominate the O and basically cancel it out even though it is still there in the genotype makeup, it's just dormant so to speak. On the other hand, if you combine an O with an O, (the lower case i's) then the result is just going to be type O blood (represented by the two side by side lower case i's inside the square).

[@istel3283]

Thank you so much this was very helpful to me cuz of Genetics Exam.

[@citlalivillegas9298]

bruh this video was elite.

[@masterpalladin]

Peter D'Adamo also compiled the "Genotype Diet" There are six so far, The hunter/gather usually blood type O, hunters can only O. The Explorer and teahcer, explorers can be universal so any blood type but almost always RH negative. Teachers are usually Ab+ or A+ sometimes B+, then theres the warrior,usally Ab+,A+ and sometimes B+, finally the omnivorous nomad, usually B+ and sometimes AB+.

[@LyndseyMayhew]

Is there a podcast of this please? TIA!

[@yingzhenang7678]

You're great!exactly wat my teacher taught in sch:)

[@hongry-life]

Could the blood type have to do with some kind of density in the blood also? 'A 0 B' like the 'A 0 V' spectral density of stars for example? Also in language the B developed from V.

[@belkisb.4779]

Thank you so much. Very easy explanation.

[@jasper4245]

I am A+ which means I have A antigens and I have rh antigens. I can receive any blood type except B and AB.

[@dayaaliyuhamisu4095]

Yes. I am A+ either.

[@sdelama]

So, if I may ask, have you heard of the blood type diet? If so, what is your opinion about a diet for a specific blood type? There have been several different people promoting this diet-not just one-so it seems to make sense that food would affect each type differently-but I am not a medically knowledgeable person.

[@tersitshimelash7193]

With out you bio class wouldn't be fun! Thank you so much for taking your time and posting all these videos. Oh and yes it is helpful! I always liked what you say at the end "I hope that's helpful. :-)

well this video make me really understand about blood type and rhesus.

[@salvodipter]

Thank you very muchfor this nice and clear video ;D I really enjoyed this!

[@nopopaul5703]

Thank you sir for all what you share

[@myRefuge3710]

4:04 and 1:23 and 2:35? So if O blood can except any protein, how can it not except AB antibodies? Thats conflicting. Can someone explain this?

[@coffee-xg6my]

Type O blood has no A or B proteins (antigens) on its red blood cells, so that's why it has created antibodies that are trained to be on the look-out for any blood cells with those A or B antigens that may intrude their blood stream. It sees them as invaders because they do not belong in its own blood. So, if you try to transfuse A, B or AB blood into the type O blood, then those antibodies in the type O blood are going to say "hey those A & B antigens are not supposed to be in here because our own blood doesn't use those. So they will attack them. So, because of that, the only blood that a type O person can accept is other type O blood, because it's the same kind of blood as itself and won't get attacked. And also, if it's type O negative blood, then it can only accept type O negative. If it's type O positive, then it can accept type O positive or negative. But nothing else. Type AB blood on the other hand, has both A & B antigens on its red blood cells, so it hasn't created any antibodies that would attack those antigens. If it did, then it would be attacking its own cells, and the body doesn't want that to happen. So, there's no need to have antibodies in type AB blood.. The A & B antigens are part of its own blood and are supposed to be there. So, because of that, the type AB person can accept any type of blood, because like I said there's no antibodies in there to attack any new blood cells that enter. AB blood says, "all blood types are welcome here, so come in, there's no danger of you being attacked because I don't have any antibodies that will attack you!" A person with AB blood can accept all types, A, B, AB or O with no problem. Because his blood already contains the antigens of those types A & B. And of course type O is no problem because it has no antigens at all to be attacked. And if it's AB negative, then it can only accept other negative types. If it's AB positive, it can accept ALL types, positive and negative. Note: If you are wondering, then why don't the type O antibodies attack the A & B blood antigens when type O blood is transfused to an A, B or AB recipient?, Well, that's because the antibodies for blood are in the plasma (the liquid part of the blood), And when any type of blood is donated, it is run through a process that separates the plasma away from the red blood cells. So, when you get a blood transfusion, you are only getting the red blood cells but not the plasma that contains the harmful antibodies.

[@sciencenerd7639]

The A, B, and O antigens are oligosaccharides, not proteins (and no, they are not glycoproteins because the oligosaccharide can possibly be attached to a lipid, making a sphingolipid). Also, note that the O antigen exists (well they call it H antigen), but practically no one reacts to it, so for simplicity we draw the O blood cells as if it had no antigen. The O antigen differs from the B antigen and A antigen by one sugar residue. Rh antigen is indeed a protein.

[@allanochoa4826]

little bit confused, on 2:52 wouldn't type "O" have antibodies for blood type "A" , so type "O" would attack blood type A

[@shadowslayer6526]

type "o" has got no proteins attached to its surface.

[@tuni31]

When we talk about blood transfusion, we actually mean red blood cells transfusion. Those antibodies are in the plasma, that's why you can't donate O plasma to an A (or B) recipient. ;)

[@nimitgandhi9]

Awesome video. I finally understand it now!

[@David-zi9nr]

Why would it be beneficial to have b or a blood antibodies? Why did we decide to have antibodies for other blood types?

Do you have any videos over epistasis/codominance/ incomplete dominance

[@jackiebird774]

Very informative and easy to follow thanks :-D

[@allantalver]

Very good explanation, but I have one question. If for example O blood gets transferred to someone with A blood, why won't the A antibodies in O blood have a negative reaction with A proteins on the recipient's blood cells? Or doesn't it work that way? And basically the same question for other similar conflicts with B and AB recipients. Thanks!

[@SreenikethanI]

I have the same question!!
