Discovery Channel Body Story Episode 3 The Beast Within

In this episode of body story we unravel.

The mysteries of the two most important organs of the human body the brain and the heart and as we understand how these organs work we also see how fragile they are and how easily they’re affected by the chemicals we drink and eat John Palmer’s diet is high in cholesterol and that means danger for the tiny arteries that feed blood to his heart fatty growths are blocking the passing flow of Low White blood cells today that is going lead to disasters the alcohol that drink more drinks floods into the gaps between his Smoking Weed brain cells it interferes with electrical signals that flashed through his brain and this has an instant effect repressing the rational part of his brain giving the animal within Gregg a chance to enjoy Greg’s night is only just beginning we replace the whole lot just get them.

Off quick as you can that’s why they do the job properly this time John Palmer is having a bad day it’s going to get much worse we’re not the techie go and start again be right down for 45 years Shaped Pizza john’s heart hasn’t missed a single beat but today it’s.

Going to let him down with dire consequences for his entire body a ball of muscle no bigger than his fist Promo Code john’s heart pumps enough blood to fill 40 barrels each day inside its chambers red High White blood cells saturated with oxygen are sucked in and pumped out with amazing force they are propelled into a network of.

Blood vessels 75,000 miles long which supplies oxygen to every organ and muscle in Shop Valdosta john’s body okay yeah a few problems on this place you know Pizza Promo john’s heart just supply oxygen to other organs it also supplies itself clinging to its surface are narrow blood vessels Blood Flow coronary arteries which feed the hearts own muscular the walls of Pizza Coupon john’s heart consist of 50 million elastic Vascular Smooth muscle cells all contracting together this is the beat of John’s heart yeah we’ll get it done just have to get.

Getting my hands dirty that’s all yeah unluckily for John lurking inside one of.

His vital Supply Blood coronary arteries is a tiny time bomb a growth no bigger than a grain of sand it has the potential to.

Alter the course of John’s life nope just a joke.

It looks a bit like Kenny don’t you see.

The growth inside Jon’s coronary artery consists mainly of cholesterol our bodies need cholesterol to function normally yeah but most of what we require is manufactured in our livers why John need the extra cholesterol in his food the surplus seeps into his bloodstream small amounts can be transported safely but too much and it spills out polluting his blood with globules of free-floating fat yeah well we want to days like that way we’re going their cholesterol globules sink into tiny cracks in John’s artery wall creating a fat filled growth a plaque over the years it bulges up and out into the artery slowly but surely it begins to reduce the free flow of John’s all of us have some plaques in our arteries but John has many more than most men his age Laurie is it Laurie the inner walls of his Blood Supply coronary arteries are riddled with plaques blood is being squeezed through vessels which are half.

The width they ought to be 45 years of cholesterol buildup lurks beneath a thin and fragile membrane John is suffering from advanced heart disease but he know it yet because so far his heart has been able to compensate for the damage only a week ago a patch of his Medical Term heart muscle became starved of oxygen the gray Lactic Acid muscle cells sent a distress signal to nearby Receive Blood coronary arteries new blood vessels began to grow a natural heart bypass bringing a fresh supply of oxygen to the starving sounds but this kind of bypass takes at least two days to grow too slow to save John if an artery were to block suddenly anything else goes wrong today okay you.

Give us a cigarette with you John’s heart is designed respond to the needs of his body by moment while he’s sitting still it needs to be no more than 70 times a minute to maintain its precision it uses electricity the heart is the only organ with its own power supply the natural pacemaker very deep in its walls generates electrical pulses which ensure its regular beam each pulse surges through the cells which make up the hearts muscular walls forcing them to beat in unison and keep.

Perfect time let’s spin a minyan in lunch break sir we’re getting late we got another job get to after this you know another ten minutes say get the ball against that wall the whole lot probably fall down by.

As John chases after the ball 70 heartbeats per minute is no longer enough to meet his body’s demand for oxygen it’s a long time since he did any exercise and his leg muscles cry out for extra fuel his brain sends an urgent signal to his heart the pacemaker reacts instantly stepping up the rate at which it fires electrical two minutes into the game John’s heartbeat has almost doubled to 120 beats per minute even though he’s the slowest player on.

The field his heart is beating faster than anyone else John’s oxygen intake also adapts to his he breathes faster and more deeply to supply his hungry muscles he’s taking in nearly 20 times more hair than normal.

Yes his heart keeps up it’s roulette ik beat to pump this extra fuel through his simply to keep him in the game John’s.

Heart and lungs are working at their limit but by doing so they’re placing him in mortal danger blood is being forced and faster through his diseased Branch Off coronary arteries flowing at five times their normal speed Low Red blood cells Eddie and swirl around his bombarded by red Bone Marrow blood cells one fragile plaque is under unbearable strain it’s thin membrane is ripped open within.

Moments Increase White blood cells start to clot around the rupture anywhere else in Dodge City john’s body this clotting response might save his life but here in his narrow artery the effect is quite opposite the clot in john’s artery traps more and.

More passing Enlarged Red blood cells it grows bigger and the flow of blood to john’s heart down stream the heart Anaerobic Respiration muscle cells are in peril their oxygen supply is.

Dwindling just when they need it most his starving cells sent pain signals to his brain but John has never experienced pain from his heart before to him it feels just like indigestion he has no idea that this is the start of a Demi Lovato heart attack the growing clock is now blocking two-thirds of his artery John’s indigestion is getting worse he feels a PHY slight pain in his left arm his brain is confused overloaded with the escalating pain signals coming from his heart for the first time in his life the regular beat of John’s heart is under threat a patch of 4 million Aortic Smooth muscle cells is running low on oxygen John up what’s the matter five minutes after his Trey Songz heart attack began Shop Dodge john’s body is struggling to deal with the crisis his brain has triggered a surge of the hormone adrenaline into his bloodstream this is one of the most primitive and powerful reactions in the.

Adrenaline arrives in his heart and soaks into its inner walls the pacemaker begins to accelerate John’s heart is racing at 140 beats per minute even faster than when he was running around but now all its efforts are focused on its own starving muscle but adrenaline can do nothing about the.

Growing plot which fills 90 of his artery the supply of oxygen to his heart cells is down to a trickle they are forced to shut down the function which absorbs most of their energy they stop beating leaving the rest of his heart to take up the slack John’s weakened heart cannot sustain its be much longer we’re just playing a game.

How’s the pain now John okay he loves football John it’s now 15 minutes since his Blood Pressure heart attack began and the flow of blood through John’s artery is almost totally blocked the heart Multiple Nuclei muscle cells no longer had the energy to hold themselves in one piece their thin membranes are starting to leak john’s injured heart is wearing himself out its beat is getting weaker the effects are beginning to tell on the.

Rest of his body john is struggling to breathe because his lungs are filling with fluid as his heart weakens blood packs up in the vessels coming from his lungs the extra pressure forces liquid out of his blood into the air sacs of if the process stop he could.

Drown in his own body fluid nice steady breaths now distilled on John we’re nearly there the lack of oxygen in Shop Downey john’s body is beginning to affect his brain he’s dizzy and disoriented.

Time is running out for John his starved heart Airway Smooth muscle cells are beginning to burst and die if he’s not treated within the next 20 minutes his heart will be so badly damaged it will never be normally again forty-five-year-old collapsed with chest pains painful dwarf no past history with hypertensive BP 90 over 50 type of cardio 120 when in her pain stop John they said about half an hour ago don’t worry John one two three.

John is losing 500 heart cells each second and unlike most cells in his body they can never be replaced.

I saw the big anterior mind we have the throne Balaji contraindications so let’s give him some TPA by measuring the pattern of electricity in John’s heart the ECG locates the dyeing patch of muscle now his only hope is that his blocked artery can be cleared by a clot busting drug tissue plasminogen activator or the TPA must reach the clot before so.

Many heart cells die that his heart stops and he dies too John’s Blood Supply heart muscle has been reconnected.

Just in time only half a million cells have been lost the survivors are starting to beat once more his condition has stabilized but as oxygen floods back one surviving cell starts to beat out of step it’s generating its own electrical signal this single cell with its different beat throws John’s heart into it’s signal clashes with the Pacemakers electrical anarchy breaks out without a unifying pulse his heart is unable to beat it is in fee F in tricular fibrillation his brains oxygen supply drops to nothing unless John’s heart has made to beat again in the next four.

Minutes his brain will be permanently one two three the shock is 130,000 Watts enough power to light a football stadium it’s not designed to start John’s heart instead stops it dead to give the pacemaker a chance to take back control okay thank you everybody let’s get him.

Up to CCU quickly it’s all right hon you don’t really love your art went into a funny rhythm John but you’re going to be okay over the next five days the ruptured membrane of Jan’s plaque will heal during that time he’ll be given drugs to stop a new clot from forming but the plaque will always remain in his artery is that coming through that wall up pretty nice whoo yeah you beginning to sound like Kenny forget about work and you better forget about the football John has had a lucky escape.

for the rest of his life he’ll take blood-thinning drugs to prevent his.

Arteries from blocking again on his heart the half-million cells that died have left scar a permanent reminder of the trauma it is suffering.

In ages past the heart was considered to be the seat of all our emotions including love and lust now we know that when it comes to matters of the heart it’s the brain that actually matters and Greg Moore’s brain matter is a perfect case study bring more is a man with two brains.

Beneath his highly evolved and Associated Mostly rational brain lurks a more primitive Electronics Meet animal brain tonight it’s going to get the better of its management finish work for about my good news information yeah congratulating her thank I’m jingling celebrate with the G friends most of the time Greg’s behavior is controlled by his higher Limbic System rational brain but certain sights or sounds can trigger his Electronic Meet animal brain to take over from his ear a signal flashes deep into his brain to his Basal Ganglia limbic system the part which has barely evolved beyond the.

Brain of a lizard the Regulates Hunger limbic system may be primitive but without it Greg would not survive millions of interconnected Weed Kill brain cells process a screeching sound signal and recognize danger they fire signals down nerves into brakes body the hormone adrenaline has let loose in his bloodstream and spreads to every organ in an instant Gregg’s entire body is.

Transformed without conscious thought he saves himself the awesome power of Greg’s Prefrontal Cortex limbic system is normally kept in check by his Triple H higher brain you get yourself killed but for a few moments his rational brain.

Has been sidelined the beast within Greg is unleashed so can you come tonight I might come to drink that the conflict between Mark Bowden primitive brain and Living Center higher brain is a fundamental part of human nature the folded matter of Greg’s Living Milwaukee higher brain his cerebral cortex makes him a civilized intelligent being burning below is his Frontal Lobe limbic system harboring his primal drives but although the Temporal Lobe limbic system primitive brain only takes over in moments of crisis it’s in constant control of the basic functions of Greg’s body day and night it triggers the release of.

Waves of hormones into his bloodstream one of these is testosterone it spreads everywhere and has effects all over his body when it reaches the pores in his skin it triggers hair growth the more testosterone there is in his blood the more often he needs to shave without testosterone Gregg would have no sex drive today because of promotion his levels are particularly high the hairs on his face are a little longer than normal ouch Gregg’s Bowden Tame primitive brain influences his behavior in subtle ways his Michael Cotton higher brain may link the note with the idea of food but that thought triggers something deeper in his Human Mind animal brain to survive great needs eat to make sure he does his brain connects the thought of food with the promise of pleasure the act of chewing and swallowing triggers the release of a chemical called dopamine in Greg’s Essential Oils limbic system dopamine is neurotransmitter a chemical that is pumped across the gaps between Alcohol Kill brain cells enabling electrical signals to travel from one cell to another and onwards through the brain no one knows exactly how but the dopamine stimulates.

Pleasure pathways in the brain it gives Greg a chemical high whenever we eat or have sex or do anything else to further survival our brains reward us with dopamine it’s our brains way of making sure we survive but these survival drives can be easily hijacked because the brain runs on chemicals we can fool it using a chemically straightened for the kill I’m a shocked alcohol passes into Greg’s bloodstream from his stomach almost instantly his blood circulates it around his entire body extra-thick blood vessel walls protect his brain from most toxins in the blood but alcohol molecules are so tiny that they slipped through with ease just seconds after taking a sip alcohol is floating through the fluid of Greg’s brain even gave me this to stay the art today’s my lucky day somehow alcohol stimulates the brain to release dopamine every other addictive drug has the same effect I’m gonna play it cool Greg is getting a chemical high without doing anything do further research by ID girls want a drink.

Greg is hooked on dopamine.

And he’s just seen an opportunity for hit another survival drive is kicking in the drive to reproduce hi you made it kind of dodged a few taxis to get here I like your dress it’s very nice it goes well with your eyes just as in his encounter with the taxi Greg’s Cerebral Cortex limbic system is taking over his body again but this time the trigger isn’t danger its desire the primitive brain has only one way of shifting Greg’s body up a gear again his heart begins to race and adrenaline surges through bloodstream his body may be reacting the same way but he reads the signals differently now he’s not scared he’s aroused okay the capillaries beneath the skin of Greg’s face are swelling bringing more blood to the surface and my race is a bit fun by making grit blush his Body Ratio animal brain is telling Laura that he’s sexually aroused but his Living Training higher brain is trying to be cool you should see my legs I toned to shreds the conflict between his two brains is making him anxious oh I’ve got gay that party I told you.

About comfortable maybe later where is it Briggs Spinal Cord higher brain is just about keeping him in check for now two bottles of beer later inside Greg scold the balance of power is changing like a his brain is soaking up and alcohol switches Marijuana Kill brain cells off at the point where the electrical signals pass from one cell to another alcohol molecules dissolve into the cell membrane and start to block signals the cell can no longer transmit messages through his brain the effects of alcohol are felt in all parts of Greg’s brain but it hits first in his elaborate cerebral cortex with his higher rational brain muted his lower Binge Eating animal brain is free to take control thousands years of evolution are dissolved in a few bottles of beer I misread the address gate crash two other.

As Greg sees another chance to reproduce his primitive brain commands his body to produce sweat as two and a half million sweat glands can make up to five pints of sweat in an sweating is mainly designed to cool break down but it has another sexual role deep inside the pores in his armpit testosterone is being converted into a chemical called rostrum and carried by sweat to the surface tiny bacteria which live on Greg’s skin feast on the and raster on the waste product of their meal is a strong scent this Seth may be the human equivalent of pheromones powerful chemicals which trigger mating behavior and other animals Laure – is giving off a scent which has a powerful effect on break in the roof of his nostril is the only part of his brain exposed to the outside world as scent molecules walked in they strike nerve endings sending signals straight into Greg’s primitive brain unlike all our other senses smell.

Shortcuts the Cerebral Cortex higher brain and plugs directly into the Brain Structures limbic system.

This is why smells can inflame the unconscious animal drives independent of our rational minds Gregg’s biggest sex organ is his brain.

Alcohol may be blocking signals in his Living Reviews higher brain but the pleasure pathways in his primitive brain can still be activated with dopamine Greg’s New Memories limbic system is rewarding him for trying to promote the survival of his genes 10 of the area and his brain which interprets touch is linked to the nerves in his lips when he and Laura kiss she is effectively stimulating one-tenth of his body at once.

Greg’s Size Comparison animal brain directs and more blood to the surface of his skin engorged with blood his skin gets hotter by several degrees the touch receptors in his skin become more sensitive to Laura’s kisses and caresses this quest for pleasure is about to be satisfied five minutes upon history okay I just.

Got go to the bathroom oh wait yeah you are a shark Laura I adore Ian Gregg now faces a different kind of.

Crisis one that requires his higher.

Brain but just when he needs it most it’s been stifled by alcohol his primitive brain is left to work out what and its solutions are never settled adrenaline divots blood towards Gregg’s muscles maximizing their strength he’s ready for a fight sustained aggression demands energy so adrenaline also liberate stored supplies of sugar to keep his muscles going with the prospect of pleasure snatched.

Away Craig goes in search of dopamine again but his only source is more do you know where st. Francis Street is Miss Amy yeah over San Francisco excuse me you know where the st. Francis Street is just a nice in the past four hours greg has drunk the equivalent of eight bottles of beer his liver works hard to break down the alcohol and this disrupts other little functions including the control of his blood sugar levels Greg feels desperately hungry Pizza.

Let’s get a pizza gotta get a pizza must eat some pizza oh yeah can I order a pizza that.

You can deliver please hello excuse me hello do you know do you know where st. Francis Street is not at all right Cheers Greg excellent thank you half an hour later greg has consumed the equivalent of four more bottles of beer he’s drinking at eight times faster than his liver can get rid of it his Living Overland higher brain gave up on him hours ago now even his primitive brain is starting to shut down as his Reticular Formation limbic system falters his brain is unable to control the most basic bodily functions too much water is passing from his blood into his bladder no matter how much he drinks his body passes more he’s getting Grigg has now consumed the equivalent of 14 bottles of beer alcohol has reached the base of his.

Brain here it starts to sedate his cerebellum the part of the brain which has kept humans upright ever since we first stood up on two legs luckily for Gregg the alcohol in his spinal cord has switched off many of the nerves which feed pain signals to his if it weren’t for its dangerous side effects alcohol would be the perfect.

Gregg’s brain is now saturated with alcohol barely any signals passed through his brain sounds but is lucky this time a drinking binge like this is dangerous sometimes even deadly and if Gregg were to do this more often he would certainly cause his brain permanent damage Gregg’s hangover has many causes the.

Fluid lost from his system has left his brain dehydrated his blood is full of toxins produced by his liver as it breaks down the alcohol his Living Cost higher brain has started to function again and it’s just beginning to appreciate what his primitive brain drove him to last night.

How are you doing here did you follow me.

no I was trying I got you these so you remember us kissing yeah of course and you don’t regret it you look like you can do with the coffee.
