Well, rights number. Kate asked about antibody screening done along with pre transfusion blood typing on. And so our answers. D right. So the the other test is making sure that there are no and two bodies ah, produced against antigens other than the and be indigenous. Right? So our answer is de see when the bodies other than the view I mean, this helps basically with the further ensuring compatibility.

All right for this question. We got to diagnose somebody, and after I identify which leukocyte, they're gonna have the most of based upon their symptoms. So they have allergy symptoms, and I'm just gonna write that there, and we'll come back to what those symptoms might look like. What we're gonna do is in your chapter. It identifies different Lucas sites and says specifically what they, um, attack. And so whatever they attack, that's when most of them are gonna show up. So one type Oh, are Monta sites, mon asides, fight off viruses, fungal infections, tuberculosis and some forms of leukemia. All right, and then neutrophils, uh, in general, just fight off infection, specifically bacteria and then natural killer cells. These are specific immunity sales. They could fight off, um, viral cells and other foreign invaders. Scroll a little bit here, and then bass Ifill's respond to inflammation. Produce an inflammation response. Now, if you think about somebody that has an allergy, they're not being attacked by a virus or bacteria or any of those things. So none of these are actually be right. What happens when you are allergic to something as you could have an allergic reaction and inflammation can happen, right? So if you see someone eat something, um, they're allergic to it can be scary because the broken swell up. Oh, or if someone's allergic like a bee sting, their body can swell up in whatever part they get stung by, well, that is being caused by this inflammation response specifically from basil fills. And so someone that's having an allergic response like this patient is going to have an increased amount of basic feels that be your correct answer.

For this problem. We're gonna think about hypothetical situation with the person has type a blood. We're gonna bother about Rh factor positive or negative right now where it's gonna think about. Okay, so we're gonna discuss two things that this patient has. The first is its own cells only. But their owner blood cells express the A antigens, and they're going to make antibodies specifically against they be indigent. So these air anti B, because the body is not gonna make it anti a because then those antibodies would view its own red blood cells without which have the A introgen right here and to generate here as foreign. So essentially, the body's gonna recognize anything except its own Selves, which have a as for it, which is why it produces anti beat. This is because bacteria can have, um, structures on the outside of their cells that nearer. Um, Airbnb surgeons. So that's why our body produces some of these cannula tip blood. Yes. So, again, this

When you are vaccinated against african, what kind of immune response will you get? Is it? It needs immunity, immunological memory. A responsible defense is an autoimmune reaction or systemic information. Right. First of all we can rule out autoimmune. You're being vaccinated against the pathogen. The immune response is going to be against the pathogen. Not against your own proteins. Okay. But what kind of immunity you get from vaccines? Well, this is an antibody response. If you're vaccinated you get the production of antibody. So you're looking at the adaptive immune system. So it's not an eight. We can rule that out. Let's look at the others. It's not information that's part of innate. It's not defenses because defenses are released as part of the innate immune response. I've been released by Feeling Services. Which leaves our answer the immunological memory. You remember the pathogen thickness you have memory b cells that are capable of producing antibodies to it on short notice. If you encounter
