Where a Vampire Should Bite (Because Science w/ Kyle Hill) 

Thigh biting vampires... That would be like, 50 Shades of Red.

Okay, I'm a little late to this episode, but this is actually so helpful. I'm writing a novel with vampires and trying to explain as much of the vampirism disease by science as I can, so this is super, super helpful when one of my vampires is draining someone right before they turn them. It's weird, I know, but this is really helpful. Thanks Kyle.

Now I understand what arteries to keep away from my enemies. Thanks Kyle!

Speaking as a professional vampire (that is, a phlebotomist) you missed some spots. The prime one is the crook of the elbow -- there are three main veins there and most people have at least one of them that's prominent. But if your victim has tiny or very deep-set veins, you can go for the veins in the back of the hand (which become more prominent with age.) Plus, a hand is much easier to get at than a neck.

I feel far too mortal after watching this.

Allllll of the sexies. Thank you, Science Thor, for another great video.

I'm totally loving the Thor hair. (Serious cosplay opportunities.)

Wow Kyle, what a sell out. Helping out those vampires to save your own backside.... not cool, man.

I believe that a vampire would HAVE to go after veins rather than arteries because of the simple fact that a human/vampire's mouth couldn't stay attached to a human body because of the force of pressure blood comes out of an artery such as the carotid artery when sliced or punctured

Arteries generally have a smaller diameter than veins. The pressure is higher but arterial walls are thicker to support the higher pressure. This thickness is why doctors do blood draws from veins, as the arterial walls are hard to puncture. Maybe vampires would prefer veins for this reason.

I love this so freaking much. Not just the science, but the puns man, the puns!

lmao when he said "Ive got the hair already and everything...."

size is very dependant my nerdist friend. im a PICC RN and access vessels all day (11yrs +) under ultrasound...many times the companion veins to an artery can be larger. Genetics, mileage and disease process play a part. Much geek love

"And biting there is still... all of the sexies..."

So Kyle, planning on investing in a scarf/turtleneck factory?

Hey! Vampire science with discount Thor...YAY! :D

I came here for the Thor hair,but i stayed for the content

A injury to the vena jugularis interna would cause an possible air embolism caused by the high negative pressure of the heart. A bitte to the arcus palmaris superficialis wold not look that cool, but still nutrient and oxygen rich blood. To treat the wound its easy to compress the limb to stop excessive blood loss. Nice idea for a video though.

I always thought that a Vampire's venom also contains anticoagulants making the blood flow more freely around the wound... Just my theory...

blood plumbing sounds like a bad alt rock band or a bad slasher flick

I recently discovered you and your channel. I've watched a few of your videos and I have to say that this is the video that made me laugh in delight more than any other. The corny jokes which inspire me and my humor crafted from farmers from Kansas, not mentioning your accents and various gags. What I'm trying to say is, you're a funny guy and keep up the great work. Making nerds proud.

kyle,kyle,kyle, kyle hill the science guy

that scene of angel from buffy, I remember seeing it and thought it was pretty awesome. loved that he got the smoke from the bite too. awesome affect.

buffy references make everything better

So a vampire wouldn't be arrested for biting someone in the neck?

"so whats really at STAKE here" i got u buddy, nice one

kyle, You remind me of Felicity Smoak from arrow, for some reason xD

"I'm not a doctor. I'm just a science...guy" (flashes smile) Yes, that was all I needed. I'm turning my computer off and and going back to college...after two more videos.

What about biting the wrist? Doesn't an artery or something flow there?

"What's at stake for you guys" is all I needed to subscribe brb crying

While the aorta retains most of the luminal diameter directly from the left ventricle before the branches of the coronary arteries, it still retains most of the diameter as it transverses to the back of the body through the abdomen. The biggest problem would be sinking your teeth around the spine, back hair and fat and the epaxial muscles to get the descending aorta. Additionally, the idea of sticking your mouth between someone's legs blinds you and exposes your own neck to paralysis or amputation when feeding. As such the best feeding position is to rest your head on another person's shoulder as a visual perch that retains peripheral vision while allowing easy access to a vulnerable, bone restrictioned site to hunt and kill your prey quickly.

I am so proud of myself -- I knew most of this already. Yay.

Seems like the super unsexy vamps from The Strain would be the most successful. I self thrusting stinger is way most effeccient.

Arteries have a larger diameter than veins? This is completely untrue. If you were to examine the average internal jugular vein next to the average carotid artery, you would see it was much larger even in external diameter. Take into account that arteries have much thicker, muscular walls, and the internal diameter of arteries is even smaller in comparison. The idea that a vampire could penetrate down to the internal jugular vein with the typical fang length seen on TV is laughable. The more available vessel would be the much smaller external jugular vein, which can often be seen just under the skin of thinner individuals running down the anterolateral neck bilaterally. However, the pressure and flow rate through this vessel is so low that the vein would collapse under almost any amount of suction, making it a terrible place to feed from without a significant rent in it. This is why more realistic portrayals of vampires show them essentially ripping the necks of their victims open to feed in order to access the deeper arteries and veins where flow is adequate (thus killing them). True Blood has shown vampires feeding at individuals' groins, presumably from the femoral artery or vein. These vessels even in thin individuals are quite deep and essentially unreachable without a potentially fatal injury. Even two puncture marks as small as canine teeth in the femoral artery is potentially fatal considering the pressures within these larger vessels (as he alluded to above). And yes, I'm a surgeon who has accessed and operated on these vessels innumerable times.

''They'll probably survive... Im not a doctor... Im just a science... guy'' 2:31 DAT Face XD

"Talk to Blade?" B-But he hates Vampires more than anyone!

Either Kyle's getting into the Halloween spirit or he's been really enjoying this season of American Horror Story so far. Or both. Probably both.

"i got the hair and everything..." i love your close up man

well i don´t personaly go for arteries it gets messy realy quick and bloodstains on clotches are realy hard to wash but that is just personal preference altho if you are in a hurry you rip them to shreds anyway so ..

I have always maintained that the best bite targets for sucking blood while keeping your "donor" alive are the mass of capillaries in human breasts. You would get a controllable flow of still-oxygenated blood, and the layers of fatty tissues in the area would contribute to a richer, creamier mouth-feel. (Some credit is due to Type-Moon's vampire-related video game, Tsukihime. Though it's not actually a vampire which is feeding in this manner. I also like saying the title of the versus fighter sequel, Melty Blood.)

do you have an episode on dreams if not please make one

I remember hearing somewhere that vampires bite people on the neck because it's easier to break through and is in a less uncomfortable spot.

can you do a video on Mystique's shapeshifting ability?

Sorry about the double post...blame RU-vid for NOT letting me edit.Also, regarding Vampires, would a video of a sunrise kill one? How about a photograph? Would a wooden arrow through the heart do the job? If so, would they laugh at an aluminum arrow? Could you make a wooden bullet that kills Vampires? Obviously, I'm talking about real Vampires, not those Twilight wusses. Thanks again.

If a vampire were to bite into an artery, such as the carotid or even aorta or femoral arteries, assuming that they're similar to humans in this respect, would they be able to swallow that much blood that fast? Sure veins are at a lower pressure and wouldn't actively 'spurt' blood like an artery would, but if you're getting more blood than you can swallow at a time, it's just going to make a mess and go to waste! Also, are stomachs big enough to hold all of the blood one could get from a person? Especially if breaking into an artery, I imagine they would get very close to all of the blood in circulation before the heart actually collapsed and stopped pumping (as I'm sure you know, the heart pumps on its own and will pump even if the brain is dead). I don't know off the top of my head how much blood a person generally contains, and have no idea how much liquid a stomach can handle all in one go. Might be plenty, but I've got no idea. More science on the vampires!

Thanks for the pointers Kyle. *Maniacal laughter*

Kyle has a fundamental misunderstanding of verbal inflections . But dear god his videos are addictive.

way to go kyle, you've just killed us all!!!

2:28 kile: I'm not a doctor I'm just a science guy Me: bill nie the science guy

omg, i completely forgot Angelus did that. That was badass.

My neck hurt throughout the video... Thanks! By the way, I'm a major fan and started putting science in the Jurassic Park and Jurassic World trilogies (even though one Jurassic World movie has been released). I couldn't thank you enough!

"at stake.". I get it. I love it. I subscribed a friend. It's Priceless. I will never leave you Kyle Hill. Because, You get it !

Why y'all saying "Bite the dick"? And it's DUDES throwing it out there, tf wrong with y'all? LMAO

how are you suposed to bite the aorta?? its behind the chest and right next to the heart, you would have to open the persons chest and by that time they would probably be dead already.

blahaha "talk to blade" lmao that got me!!! XD

if i could only have one hair style for all of eternaty, like in interview with a vampire, i would pick Kyle's thor hair.

...you seemed so proud of that "at STAKE" joke... haha, I'll sub, why not.

Couldnt biting on the arm like where the thing runs above your elbow also be a good spot if you just needed a little bit of blood

im english and we have arteries and capilleries, they are two different things in biology, one type (capillery) is closer to the skin used generally for heat control, (moving closer to the skin when body temperature is too hot to radiate heat away from the body and vise versa) and the other (artery) is either bringing the blood back to the heart or outward from it (cant remember which right now)... at least i think thats what they are, capilleries are also a lot smaller

Here's an idea for one. What the most painful fatality there is from Mortal Kombat.

Nerdist: Makes a video for vampires. Vampires: TELL US SENPAI! *scribbles notes*

Cirque de Freak did the "becoming a vampire" thing the best in my opinion. Instead of a bite, it's a blood transfer.

The stake joke just gold

lol "I got the hair and everything".

Thanks for what I should protect in case vampires attack. ...and if I were a vampire. "Yeah we cool, thanks for the info."

I always wondered since the walking dead started, can a zombie bite through denim and into human flesh? or would the teeth and gums buckle and break before that

during this entire video. I felt the urdge to curl up and hide all my important artery's. I guess that's good. its instinct

his adorable dorkiness reminds me of Connor from Primeval. >.

I like the way Vampires are explained in the Cirque Du Freak series. There 2 types. One that just 'snacks' on humans, leaving them unharmed afterwards, and one that drains their victims dry when they feed. The snackers need to eat more often, but can go unnoticed, as they don't cause any permanent harm. The snackers eat by basically, cutting open a vein with their sharp nails, then drinking. The vampire's saliva acts as a stim-pack, and speeds up healing, so that when the vampire is finished, it heals itself within seconds, repeated doses of vampire saliva like this also causes the human body to produce more blood, and become fitter and stronger as well as slightly increasing overall life span, so a lot of vampires get willing thralls that they snack on. The other type... it doesn't really explain how they do it, but I assume its basically like normal vampire, just get into the neck and drink them dry.

Additionally, preference for blood vessel is determined by vampiric dietary needs. For instance, if vampires are iron deficient, any heme rich blood cell will suffice. But if vampires maintain a greater physical strength than humans through blood doping like Lance Armstrong, the preference would be for oxygenated blood of the carotid arteries. Jugular veins would be slower than the carotids as they drain bloid from the head and be deficient in both oxygen and glucose as the brain consumes both in high quantities. No vampire would bite a shoulder except a mosquito as capillaries are not only the smallest vessels, they are the coldest and take an incredibly long time to pool blood and would likely clot before meeting the caloric needs of the vampire

I have always wondered why any vampire would get blood from a vein. All if the nutrients and oxygen would have been drained from the blood after feeding the body’s cells. Arterial blood is delivering nutrients and oxygen to the cells, and one would think that this blood would be better for the vampire.

On buffy vampires bit in every one of those places, interestingly. Im not sure how many other shows thats true of?Angelus bit the gypsy girl on the femoral artery, they seemed to go for the jugular or the cartoid just randomly, and there was definitely a mark somewhere on the torso at one point but i can't remember where

2:42 if i wasn't already subscribed, i would subscribe just for that joke.

Jingle bells Twilight smells Edward ran away Bella dies Jacob cries Team Star Wars all the way!

Oor.. go to a blood bank and drink a pack like a CapriSun?

Kyle you are freaking hilarious bro, keep up the good work!

Kyle, this video was FANGtastic...

2:31 That face though!!

can u make a vidio about if they drink blood (solid fangs) or siphon blood (hollow fangs). and if fangs should curl over the bottom lip or stay in their mouth?

Love this! You are awesome, keep being smart and awesome and teaching people things. Science!

Maybe its overthinking with that smoke thing but did u ever tryed to breathe and drink at same time? I mean if he drink blood and accidentely smoke too it wont get inhalated cuz smoke will be in stomach with blood? Just a though...

Shoulder has the cephalic vein, largest in the arm at the front, and the brachial artery as well. Both are easily accessible.

Truth be told, vampires just sort of instinctively know where to bite in a given situation. Even though I'm only half, I often find my thoughts drifting towards biting if I stand too close to someone. And as a side note, props to you for mentioning Blade. We're pretty close acquaintances.

I watch all the time but never it subscribe for some reason and your stake pun actually made me finally hit it. Good job sir

Blades gonna be pissed Kyle.

well time to gentically engineer me some titanium veins and arteries

1:20 how can more blood flow to arteries than venes? I mean its like a cycle, so what goes away from the hearth should enter it again.Can someone explain this to me?

Sure did help a lil' vampy! thanks for the dedication, too. i won't hurt yeh.

This video has made my body all tingly... and not in a good way.

how would a standard sci-fi laser blaster gun work and DO they run out of ammo?

hey can you do a video on the sdf macross and its anti gravity drive and its resemblance to a mach principle thruster.

1:20 Arteries do not have a larger diameter than vains and do not have more blood per unit time... Arteries have a thicker wall and a higher pressure, yes. But the same amount of blood has to go to the body, as is transported back to the heart. So it is the same amount of blood that passes. Same amount and higher pressure, means arteries have a smaller diameter. Look it up.

Awesome video, I'll have to show this to all my VTM buddies.

Can you please tell me which video you talked about Propheria in? I want to learn about skin that is allergic to light.

How about what is the optimum mask that would conceal your identity, but allow full range of motion and vision for fighting?

Thor does science videos now?

The more videos I watch the more I love this guy....and the more I notice.....he's like a male Felicity Smoak from arrow. Like looks, mannerisms. I just got a good laugh from that XD.

Isnt the thoracoacromial artery in the shoulder?

Thank you for helping me understand

actually the book series called Vampirates actually addressed this and had their vamps biting a humans thorax, wherever that may be.
