Try to make ends meet Where all the veins meet yeah, He knows if it were merely up to him he could change (“I can change, I can change, I can change”). I'll take you down the only road I've ever been down. You know the one that takes you to the places. Where all the veins meet, yeah [Chorus 3 + Outro] You know. All the arteries, veins, and capillaries of a human child, stretched end to end, are The amount of blood vessels in a human adult would circle our planet four a part of the eye where the cornea meets the sclera—the white part of the eye.

Think of it as a mini digital encyclopedia with a dose of wow. Beneath your skin, and deeper within your body, run networks of veins. These thin, tube-like structures are an essential part of the circulatory system, which distributes blood and nutrients throughout the body.

Eidson, a phlebologist vein disease specialist at Atlas Vein Care in Arlington, Texas, finds most compelling about veins is "how absolutely intricate and fragile the circulatory system can seem and yet at the same time be so resilient and adaptive. Three types of blood vessels make up the human circulatory system: All three of these vessels transport blood, oxygen, nutrients, and hormones to organs and cells.

While arteries carry oxygenated blood away from the heart to the tissues of the body, veins carry oxygen-depleted blood from the tissues back to the heart, and in fact have special valves that help them to achieve this directional flow. Capillaries are tiny blood vessels that connect arteries to veins and allow nutrients in the blood to diffuse to the body's tissues. Veins, small as they are, consist of three layers.

According to Eidson, these layers are known as the tunica adventitia, tunica media, and tunica intima. The tunica adventitia is the tough outer layer of arteries and veins and is made mainly of connective tissues.

The middle layer, tunica media, is all smooth muscle and elastic fibers. This layer is thinner in veins than in arteries. The innermost layer, tunica intima, comes in direct contact with blood as it flows through the vein. This structure is made up of smooth cells and has a hollow center known as the lumen. All the arteries, veins, and capillaries of a human child, stretched end to end, are estimated to wrap around the Earth about 2.

The amount of blood vessels in a human adult would circle our planet four times, equalingmiles, according to Eidson.

Capillaries are tiny—at their smallestthey're less than a third of the thickness of a human hair. But to really put it into perspective, consider that when red blood cells flow through capillaries, "[they] must travel through them one cell at a time in a single-file line," Eidson says.

You hear what he's saying? What's more, it's kind of a logical extension of the fatalism of the song. Fatalism is, let's be honest, kind of a juvenile philosophy. I'm sure you've heard teenagers groan about how they just don't have any choice in what they do, because it's just who they are, man.

Hell, you've probably said that yourself a few times, right? Basically, this kind of fatalism can often be used as a license to be a jerk to people. That's basically what the video is driving at. All this might seem pretty incredible. I mean, why would a band put out a song as poignant as Bittersweet Symphony only to make a totally ironic video that satirizes the song itself?

Why would they undercut themselves that way? Well, I think it seems a bit less strange when you consider some of the other bands from this period. Check out the video for Blur's Song 2, for example: Now, I don't think there's any way around it: So, it's double hipster, I guess. You've got a bunch of kinda dorky looking guys who are playing music that really can't be described as anything other than ironic. In fact, they're pretty clearly lampooning the hell out of the entire Grunge genre.

They're actually doing a lot of the same things--there's the dirty set, the writhing around, the emphasis on just totally dropping out of society With the lights out, it's less dangerous Here we are now, entertain us I feel stupid and contagious Here we are now, entertain us A mulatto.

And it's going to basically all kind of gather together, and again, to a giant, giant set of veins. Maybe veins are dumping in here now, maybe another vein dumping in here. And these veins are all going to dump into an enormous vein that we call the inferior vena cava. I'll write that right here, inferior vena cava. And this is the large vein that brings back all the blood from the bottom half of the body.

There's also another one over here called the superior vena cava, and this is bringing back blood from the arms and head. So these two veins, the superior vena cava and the inferior vena cava, are dragging the blood back to the heart.

And generally speaking, these are all considered, of course, veins. Let's back up now and start with the large and medium arteries. These guys together are sometimes referred to as elastic arteries.

And the reason they're called elastic arteries, one of the good reasons why they're called that is that they have a protein in the walls of the blood vessel called elastin. They have a lot of this elastin protein.

And if you think about the word elastin or elastic-- obviously very similar words-- you might think of something like a rubber band or a balloon. And that's probably the easiest way to think about it. If you have a blood vessel, one of these large arteries, for example, and let's say blood is under a lot of pressure because the heart is squeezing out a lot of high pressure blood, this artery is literally going to balloon out.

And if you actually looked at it from the outside, it would look like a little sausage, something like this where it's puffed out. So what's happened there between the first and second picture is that the pressure energy-- so the heart is squeezing out a lot of pressurized blood. And, of course, there's energy in that blood. That pressure energy has been converted over into elastic energy.

It's actually converting energy. We don't really always think about it that way, but that's exactly what's happening. And when you convert from pressure energy to elastic energy, what you're really then doing is you're balancing out those high pressures. So you're balancing out high pressures. And this is actually very important, because the blood that's coming into our arteries is under, let's not forget, high pressure.

So the arterial system we know is a high-pressure system. So this makes perfect sense that the first few arteries, those large arteries and even those medium-sized arteries, are going to be able to deal with the pressure really well. Now, let me draw a little line here just to keep it straight. The small artery and the arteriole, these two are actually sometimes called the muscular arteries.

And the reason, again, if you just want to look at the wall of the artery, you'll get the answer. The wall of the artery is actually very muscular.

In fact, specifically, it's smooth muscle.
