This question is regarding the abo blood type.
00:04
So first of all, let's look at type a.
00:08
So type a red blood cell has a antigen on the red blood cell.
00:19
So the recipient antibody is an anti -b.
00:31
So antigen is a, and antibody is anti -b.
00:48
The b is the antigen b.
00:50
So the recipient doesn't have the antibody attacking a, but it does have the antibody that attack antigen b.
00:58
Now type b person.
01:02
Type b person carry red blood cell that has a different antigen.
01:14
So it's antigen b.
01:18
And the recipient carry anti -antigen a antibody.
01:25
So you can see that type b person carry anti -a antibody.
01:32
Now the next type, type ab.
01:38
So in that individual, it has both antigen a and antigen b.
01:49
That's why we called it ab.
01:59
So both antigen a and b are found on the cell surface.
02:04
But since they have antigen in the blood, the recipient doesn't have any antibody.
02:12
Otherwise, the antibody is going to attack antigen a or b.
02:15
So there's non -antibody.
02:17
The last one is type o.
02:20
Type o person doesn't carry any antibody or antigen, sorry.
02:27
So you can see that there's no antigen on the cell surface.
02:33
So the antigen is, we call this o, no antigen.
02:40
But due to the red blood cell has no antigen, type o person has both antibody, type anti -a and anti -b.
03:00
So the antibody is going to attack both antigen a and antigen b.
03:05
So now with that in mind, let's take a look at the, whether the patient with blood type receive certain other transfusion.
03:17
Would it be safe or unsafe? so let's start with the first one...
