Is this the right place to be? Hi Joshua. If you could just stop sharing your um slides. Can you hear me? Yeah. Yeah. Yeah. Ok. Is there a way to like blur my background? Oh, I can't hear you. What about now? Can you hear me? I can't hear you. Um It's not work now but ca can can anyone hear? Yeah, I can hear you now. Great. I think we'll just wait a couple more minutes for people to wait. Is there a way to like blur my background here or? Um yes, I'm not too sure to be honest. Let me see. Yeah, I was trying to do that as well but I couldn't, we can do it. Yeah, we'll wait a couple more minutes for more people to join. Can everyone who's joined heros because I've seen someone right on the chat. Yes. Ok, great. Thank you guys. Yeah, we'll just wait a couple more minutes before we get started. Yes. Mhm. Ok. I think we're gonna make a, make a start now. Just a quick few things I'm gonna mention before. Um, so today we've got Joshua and Ian who are gonna be doing our lectures. Um I'm Harry. I'm a third your medic and I'm the question. So if you have any questions, just drop it in the chat. Um And I'll put all of our emails in there as well if you want to contact them after or me as well. Um The slides will be uploaded, there will be a recording afterwards so you guys can watch anything if you've missed it. Um And we've got part two happening tomorrow, which is starting at 10 and we'll try and end it by one. And today it's just gonna be everything that you can see on the screen, plus structure and function of airways and ventilation and gas exchange. Um So if you guys of course, have any questions, just drop it in the chat box and someone will answer. But yes, Josh, go ahead and start. Nice. Thanks. So basically today we're just gonna go through the structure uh introduction to the heart, cardiac cycle, er cardiovascular mechanics, microsul um just quickly briefly the, the most important stuff. So these are just the Tylo's I just copied this from in Sunday. Um If you guys wanna check this later, you will see it in the recording. Um If, if anyone wants to join the cement, uh they can, there are a few questions, few SBA S B AQ that you can do not leave that on for another 20 seconds. Ok. And I'll just move on now. So we're gonna start with an introduction to the heart. This is just like a nice little schematic of the heart, the cardiovascular system. So obviously, we've got the heart here. Let me get this pointer up. Let me see this laser. Yeah, you can see it, the heart here. Obviously the the main blood vessels you can see here the pulmonary artery, the aorta to perfuse the rest of the body, the lungs reoxygenate the lungs, perfuse the upper body, perfuse the lower body. Um This is just a overview uh a, a moving overview of the heart, how it pumps s er systole diastole, atrial and ventricular. So that's just to recap that breaking it down into the building blocks of the cardiovascular system. So we're gonna look at the cells in the cardiovascular system. The main cells are the cardiac myocytes, the endothelial cells and the smooth muscle cells um which they look like that fact that respectively some of their functions are to generate force for the cardiac contraction. Endothelium is mainly to line the blood vessels. And uh a large part of their, their function is to produce factors like nitric oxide to regulate the blood flow and uh BP and smooth muscle cells in do so, moving on to the layers of the heart, just keeping it quite basic from the inside
