Okay, when you understand the circulatory system, you understand how blood flows. Okay, what I'm going to do is I'm going to grab blood—well, I'm not going to really do it—but I would grab blood, maybe, and what I'm going to do is

once I grab that blood, the body reacts. Do you know what happens when you get cut? You bleed. Why do you bleed? 'Cause there's a wound? No, 'cause what your body's doing is it's trying to send blood through there so that it can clot

and it can stop. Now, why, when you get severed on a vein, do you bleed out? Does anyone know? You should know this stuff. You know why you bleed out? An open—it's an open artery. Heart pressure through your ve—very, very good. Your heart creates

pressure through the veins and through the arteries, so it's going to—weak—absolutely true. Here's the part that kills you, though: your brain. Your brain is what kills you. Black. Right? Let's say I get severed here, right? What your brain says is, 'Hey, there's no blood going in my

hand; it's going numb. Let's pump faster; let's get some blood there.' Your brain doesn't know—not—not—not that part of your brain—it doesn't know that uh there's a severed artery. It says, 'Here's the quickest one.' It severs here, right? And

your brain's like, 'I don't have any—I don't have any oxygen! Pump faster! Pump faster!' Do any—anyone seen an old Japanese movie? Looks like a blood fountain. They really do well with that. And that's really what happens. You don't bleed a little bit; it's not like

In gangster movies, when someone gets cut, the guy goes, "Oh gosh, oh no!" You don't have time to say, "Oh gosh," you're a fountain, spraying all over the place. The reason is that anytime there's a blockage,

anytime there's a stoppage, your brain says, "Hey, I need oxygen!" It starts pumping faster, pumping harder. Does that make sense? Okay, so what I do is I create that blockage. Now what's the brain going to do? It's going to say, "My arm is

numb." It's going to start pumping blood, push it there, push it to the arm. And then I stop somewhere else, and it's overwhelming to the system; blackout. It's very similar to getting choked out, actually. Not choked out... Choked out has to do with getting choked out of

losing oxygen. It's... it's very close to being strangled, being uh... having your blood cut off. Some people choke, some people strangle. We strangle, choke, and some other... cover all bases. Any... any... any questions?

Why your brain kills you.

상처에 반응하는 신체의 응고 메커니즘입니다.

정맥을 절단하면 동맥을 절단하는 것보다 출혈이 적은 이유와 심장 압력의 역할.

손과 같은 팔다리로 가는 혈류 부족에 대한 뇌의 반응입니다.

뇌는 절단된 동맥을 인식하지 못하고 심박수가 증가하는 반응을 보입니다.

그 결과 빠르고 다량의 출혈이 발생합니다.

화자가 뇌의 반응을 설명하기 위해 막힘을 만드는 방법.

막힘에 대한 뇌의 반응: 혈액 펌프가 증가하여 시스템을 압도하고 정전으로 이어집니다.
